Background & Objective: Human papillomavirus (HPV) has been associated with prognosis in patients with head and neck squamous cell carcinoma (HNSCC). Similar to the global studies, different prevalence rates of this viral infection have been reported in Iran. Therefore, we aimed to report the prevalence of this virus and its significance in HNSCC patients. Methods: Patients who were referred to the five hospitals of Tehran city from May 2018 to May 2019 were enrolled in this study. All patients were diagnosed with HNSCC based on pathologic study. The pathologic disease staging was defined, and DNAs were extracted from the fresh tissue samples via kits. After polymerase chain reaction (PCR), HPV positive samples were evaluated for determining genotypes and data analysis. Results: Of the 46 patients, three patients (6.5%) had positive HPV with the following subtypes: 18 (in two patients), 52 (in three patients), 61 (in two patients), 67, and 73. Comparison of variables between the groups with and without HPV showed a significant difference based on the tumor’s lymphatic invasion (p =0.041), peripheral lymph node involvement (p =0.008), and histologic grade (p =0.011), but there was no statistically significant difference in terms of other variables such as age, primary tumor site, size, pathologic stage, vascular or perineural invasion, metastasis, smoking, and alcohol consumption. Conclusion: HPV positivity is an important factor in the lymphatic invasion, peripheral lymph node involvement, and histologic grade of cases with HNSCC and should be further investigated for its effect on prognosis.

Background & Objective: Bladder cancer is the fourth most common cancer in men and the most common cancer in women, comprising 8% of all males and 3% of female tumors. The present study aimed to estimate the five-year survival rates of bladder cancer in Iran. Methods: Information on3,337 registered cases of bladder cancer was obtained from the Office of National Cancer Registry in the Ministry of Health and Medical Education (MOH & ME). A telephone survey was conducted to gather additional information, such as survival status, demographic, and clinical profile. Kaplan–Meier estimates of five-year survival rates were calculated according to the age of diagnosis, gender, pathological type, and provincial pole. Results and Conclusion: Overall five-year survival rate was 77%. According to the pathologic type, five-year survival rates were 81%, 66%, 81%, 42%, 77%, and 82% in low-grade urothelial carcinoma, high-grade urothelial carcinoma, adenocarcinoma, undifferentiated carcinomas, Squamous Cell Carcinomas (SCCs), and other tumors, respectively. Additionally, those tumors were 93%, 88%, 81%, 64%, and 44% among patients whose average ages at diagnosis were < 50, 50–59, 60–59, 70–79, and > 80 years old, respectively. Our study revealed that age and histological type were the major prognostic factors for survival in patients with bladder cancer. Therefore, given the histologic features of the tumor and patients with advanced age, a continuous screening would be highly warranted.

Background & Objective: Primary amenorrhea refers to the absence of menstruation in females of reproductive by age 16 when the development of secondary sexual characteristics is evident (breast development, pubic hair) or by age 14 when there are no secondary sexual characteristics are present. Primary amenorrhea can occur in several quite different reasons. Common hormonal causes of primary amenorrhea include constitutional delay, hypothalamic or pituitary disorders, chronic systemic disease, and primary ovarian insufficiency, some endocrine gland disorders, and other causes. Previous studies suggested that chromosomal abnormality is the second most common cause of amenorrhea. This report aims to measure the prevalence of the chromosomal abnormality in primary amenorrhea (PA) patients in the northeast of Iran. Methods: Chromosomal study was carried out on 200 patients with clinical features. The standard method for culturing peripheral venous blood lymphocyte was to prepare metaphase chromosomes and perform routine GTG band analysis. Results: The results revealed that 71% of PA had normal female karyotype (46,XX) and 29% showed different chromosomal abnormalities. The chromosomal abnormalities can be categorized into seven primary groups with or without mosaicism. 1- The most common karyotype was X chromosome aneuploidy (10.5%, n=21), 2- Male karyotype with or without structural abnormality of Y chromosome (5.5 %, n=11), 3- Mosaicism of turner karyotype and structural anomalies of X chromosome (4%, n=8), 4- Structural anomalies of the X chromosome (3.5%, n=7), 5- Mosaicism of turner karyotype and normal karyotype (3%, n=6), 6- Mosaicism of turner karyotype and male karyotype (1.5%, n=3) and 7- Super female karyotype (1%, n=2). Conclusion: The present study has emphasized that early cytogenetic and timely investigation can be necessary for the evaluation of primary amenorrhea.

Background & Objective: Human papillomavirus (HPV) is the main cause of genital warts and some anogenital cancers in male and female subjects which is commonly transmitted by sexual contacts. The objective of this cross-sectional study was to examine the prevalence of HPV genotypes in 10,266 Iranian male and female population, according to their age. Methods: Samples were collected from the penile and anal sites of male subjects and the vagina and cervix of female subjects in a time period between 2011 and 2016. HPV DNA was detected in PCR using the MY09 and MY11 primers, and the INNO-LiPA assay was applied for HPV genotyping. To investigate the relevance of HPV infection and age, the samples were classified into 4 age groups (13-29, 30-44, 45-59, and 60-74). Results: Totally, the most common low risk HPV genotypes detected in the studied male and female subjects were HPV-6 (77.7% and 43.3%) and HPV-11 (13.7% and 11.4%), and more frequent high risk HPV genotypes were HPV-16 (5.5% and 16.6%) and HPV-52 (3.2% and 9.6%), respectively. High burden of the HPV infection was observed at ranges of 30 and 44 years (51.8%) with a peak at ranges between 30 and 32 years. No considerable statistically significant correlation was found between HPV infection and age (P=1). Conclusion: This study gave an epidemiological overview of circulating HPV genotypes in Iranian population to develop future vaccination policies, though the findings of prevalent HPV genotypes in female subjects were inconsistent with the previous studies reported in Iran.

Background & objective: Pneumocystis pneumonia (PCP) is responsible for pulmonary infection in immunocompromised patients. This study aimed to investigating the frequency of Pneumocystis colonization in patients hospitalized in the intensive care unit (ICU) and evaluating the relationship between PCP and Pneumocystis colonization. Methods: In the current cross sectional study bronchoalveolar lavage (BAL)fluids of 100 patients were collected from surgery and neurosurgery ICUs with different underlying corticosteroid therapy conditions. Patients were divided into 2 groups (patients who received corticosteroids and not received corticosteroids). Direct examination on BAL fluids was performed by the Gomori methenamine silver andGiemsa staining techniques. Additionally, 2 filtered air samples of the 2 above mentioned units were collected. A nested-PCR targeted mtLSUrRNA gene and sequencing were used to identify Pneumocystis spp. Results: In direct microscopy, 31 out of 100 hospitalized patients (31%) showed positive results. Twenty-three (46%) of smear positive patients were from the group of patients who received corticosteroid, the other 8(16%) were from the group of patients who didn’t receive corticosteroids (P= 0.001). Pneumocystis jirovecii DNA was detected in 77 out of 100 BAL samples by nested-PCR (77%) in which 40(52%) and 37(48%) samples were obtained from the patients who received and not received corticosteroids, respectively. Pneumocystis genome was found in 1 of the 2 filtered air samples. Conclusion: A significant number of patients who received corticosteroids were also colonized by P. jirovecii that may predispose to PCP or be transmitted to susceptible patients. A significant relationship was observed between the mean hospital stay and detection rate.

Background & Objective: The spread of carbapenem-resistant Pseudomonas aeruginosa is a global concern. Metallo-beta-lactamase (MBL) enzymes cause extensive drug resistance among Gram-negative bacteria. The current study aimed at determining the prevalence of MBL-producing P. aeruginosa in Iran. Methods: A total of 43 studies were found out of which 36 were adopted. Data were collected from Google, Google Scholar, Science Direct, PubMed, Scopus, Embase, and Sciverse. The terms “Pseudomonas aeruginosa”, “metallo-beta-lactamase”, “prevalence”, “carbapenems”, and “Iran” were searched. Data from the isolates not producing MBLs were excluded from the study. Data were analyzed with Graph Pad Prism 6, meta-analysis section. Results: According to the results of the current study, 36 surveys indicated that 55% of the clinically isolated P. aeruginosa in Iran were resistant to imipenem and meropenem, among which 37.72% were the MBL producers. Among genes encoding MBLs, blaVIM and blaIMP were predominant with the prevalence of 12.91%±11.01% and 12.50%±23.56%, respectively. No report of harboring blaNDM1 and blaSPM1 by P. aeruginosa was found, similar to most of the other countries in Asia. The prevalence of blaVIM and blaIMP from burn settings were 11.50%±3.5% and 24.65%±23%, respectively. Furthermore, the prevalence of these genes was not significantly different among burn and non-burn isolates (P=0.942 and P=0.597, respectively). Moreover, no relationship was observed between the MBL production and patients’ age range. Conclusion: Approximately half of P. aeruginosa isolates were carbapenem-resistant in Iran, and approximately half were the MBL producers. The blaVIM and blaIMP were the predominantMBLs among P. aeruginosa strains, while other genes were not found in P. aeruginosa. Moreover, there was no significant difference between blaVIM and blaIMPamong burn and non-burn isolates. Due to the multiple drug resistance conferred by MBLs, detection and control of their spread alongside proper therapeutic regimens in hospitals and community settings are essential to prevent infection acquisition.

Background: The accuracy of diagnostic assays in Human Papillomavirus (HPV) genital infection and cervical cancer has remained a clinical challenge in diagnosis. Evidence indicates that a large proportion of cervical cancer can be prevented through organized care for HPV and testing. Countries with low per capita income, such as Iran and its neighbours, have no national organized program for cervical cancer screening and vaccination. The aim of this study was to review recent published papers in this region for evaluating the efficacy of released data regarding HPV genotyping system in genital infections and cervical cancer Methods: Investigating various medical search engines retrieved 46 reports, mostly after 2010, consisting of either home brew protocols or commercial technologies in this field. Results: Summarized results demonstrated that except a few cases, all reports were limited studies performed in confined populations focusing on attending patients at clinics for regular checkups. In the present study, 52.8% of papers were from Iran and the rest belonged to other countries. The rate of HPV infection was reported in the range of 0.62% to 25% in the normal population, while it varied from 18.75% to 100% in females with cervical cancer. In HPV genotyping surveys, only 26.1 % (12/46) of reports had validated and World Health Organization (WHO) proficient procedures. Also, multiple infections were not mentioned in 56.52% (25/46) of researches. Conclusions: Employing reliable genotyping methods is the best way for regular screening of cervical cancer related to HPV and precancerous diseases in females of these areas. The focus of most surveys was to come up with the best national policies for establishing a preventive program in Iran and Persian Gulf area.

Background: The breast cancer is the most prevalent cancer among women, on the other hand absence of myoepithelial cells play a pivotal role in pathogenesis of this cancer. Thus we aimed to investigate the possible abilities of the molecular assay technique to find a relationship between mammary serine protease inhibitor (Maspin) gene expression possibly secreted by myoepithelial cells, grade of breast cancer and other prognostics factors (ER, PR, and c-erb-B2). Methods: Paraffin embedded blocks of 31 breast cancer patients together with two normal breast tissues were used for IHC staining and Maspin gene RNA detection uses the real-time PCR method. Applying QIAGEN kit, we were able to measure Maspin RNA and Extract the cDNA of different samples for evaluating the Maspin RNA level. Results: We found that the RNA level was considerably lowerin these cancer samples compared with normal samples. In addition, different grades of breast cancer in the obtained results adopt some distinguishable values. The Maspin expression in samples with grades II and III is much lower than the ones in normal group (P<0.05) which could be considered as a promising way in diagnosing of this disease. The results showed no considerable differences in Maspin gene expression of the c-erb-B2 scores in the tumor group except the samples having score 0. The other observation of this research study confirmed that Maspin gene expression couldn't show any differences between the values of both ER and PR in different scores of the tumor group. On the other hand, the cDNA of these patients showed lower values compared with normal samples. Conclusion: Maspin expression was reduced in samples with grade II& III of invasive ductal carcinoma. Based on expression of Maspin Inc-erb-B2, it seems that more expression happened in normal group comparing with different scores of it. We could suggest that there was a reverse relationship between tumor formation and Maspin gene expression. These results showed possible role of Maspin as prognostic factor.

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman with laryngeal paraganglioma that initially misdiagnosed as laryngeal carcinoid tumor.

The glandular odontogenic cyst (GOC) is a rare lesion with odontogenic origin. It shows a propensity for recurrence revealed in 30% of all case. This investigation reports a case of recurrent GOC in a 35-year-old female in the anterior region of the maxilla, which is uncommon and discusses about IHC finding, surgical methods, and differential diagnosis. Under general anesthesia, peripheral bone ostectomy via large round bur for removal of remaining epithelium of the cyst wall was done. Finally liquid nitrogen was used to remaining bone. This article recommends that soft tissue adjacent to the cortical bone perforation should be excised, as well as peripheral bone ostectomy by large round bur for removal of remaining epithelium of the cyst and liquid nitrogen application to the bony cavity. Because of high recurrence rate of the lesion close follow up of the patients is needed.

Background and Objectives: Urinary tract infections (UTI) are one of the most common infectious diseases with different microbial agent and antimicrobial resistant pattern in hospitalized patients and outpatients. In order to assess the adequacy of therapy, knowledge of prevalence and resistance pattern of the bacteria is necessary. The main aim of this study was to evaluate the prevalence and the antimicrobial resistance pattern of main bacterial responsible for UTI in order to establish an appropriate empirical therapy. Methods: All urine samples were referred to Imam Hospital Laboratory, Tehran, Iran during 2011-2012, urine culture isolated and bacteria were identified and the profile of antibiotic susceptibility was characterized. Result: From 1851 urine cultures, UTI was more frequent in woman (68%) E. coli was as usual the most common pathogen implicated in UTI. Most susceptibility was to imipenem (98.9%). nitroforantoin (96%) and amikacin (94.1%) and increased resistance to penicillin (66.6%), nalidixic acid (62.1%) ampicilin (60.1%) and cotrimoxazole 54.3%. Discussion: The most common isolated pathogen was E. coli. According to antibiogram susceptibility, the recommended antimicrobial drugs are nitroforantoin and imipenem. nalidixic acid and cotrimoxazole are not recommended because drug resistance is high.

Cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. It occurs more frequently in males in fifth and sixth decades with a predilection for extremities. We report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed as pleomorphicfibroma. The tumor composed of pleomorphic spindle shaped cells with blunt ended nuclei and high mitotic activity. Smooth muscle actin was positive. In this case, the young age of the patient and previous misdiagnosis of the tumor are interesting. Subtle histologic features of low grade leiomyosarcoma can be a pitfall in diagnosis and so affects the optimal management of the patient as it occurred in previous sample of this case.

Although breast tuberculosis still remains rare, but in endemic countries should be in differential diagnosis of breast cancer and abscess. Imaging modalities cannot distinguish between cancer and tuberculosis. Acid fast bacilli stain; culture and PCR are helpful diagnostic methods but unfortunately are not very sensitive. Negative results do not rule out this diagnosis, so it seems definite diagnosis can be made by open biopsy and histologic evidence (granuloma tissues). In this case, a 33 years old woman was referred to the Infectious Ward in Imam Reza Hospital, Medical University of Kermanshah, western Iran in 2011; complaining of one lump in her left breast which did not response to usual therapy (painkillers and antibiotics). Fine needle aspiration for histologic and cytologic evaluations were negative but open biopsy showed granulomatous tissues, anti-tuberculosis chemotherapy was begun and response was significant then PCR was reported positive. We think in endemic area, empirical treatment can be started based on histological evidence and proper clinical manifestation.

Background and Objective: It is presumed that human herpes virus 8 (HHV-8) is the necessary cause of all different forms of Kaposi’s sarcoma which is the most common neoplasm in HIV-infected persons. In this study, we wanted to determine the prevalence of HHV8 infection in all the available Isfahan (Central Iran) HIV positive individuals in comparison with healthy blood donor, and also investigating the risk factors of HIV infections in both groups.
Material and Methods: Inthis cross sectional study, the samples were consisted of 50 healthy HIV –negative blood donors and all the available Isfahan HIV positive individuals (55 persons). The selected people fulfilled a questionnaire about personal demographic information. The blood samples were examined using Biotrin kit to detect anti HHV8 antibody (IgG).
Results:In HIV positive group, 10 persons (18.2%) tested positive for HHv8, but none of the control group had positive test. We analyzed risk factors for AIDS and found, as expected, strong associations between HIV infection with addiction, being in prison, travelling out of Iran, low educational status and being single or having multiple sexual partner but there is no differences between HHV8 positive and negative group.
Conclusion:The prevalence of HHV8 in HIV positive persons is high in Isfahan and preventive care may be beneficial. A future study including a large population from different high risk groups and general population in Iran is needed in order to define seroepidemiology and risk factors associated with HHV8 infection.

Background and Objective: The DBC2 (deleted in breast cancer 2) or RhoBTB2 (Located on 8p21) is a tumor suppressor gene associated with tumorigenesis. Mutational studies of DBC2 at its promoter region in breast cancer revealed an important role for epigenetic changes contributing to its low expression. Epigenetic changes through hypermethylation of the promoter can cause the inactivation of DBC2 gene. The purpose of this study was to investigate methylation pattern of DBC2 gene in the peripheral blood of 40 Iranian women with breast cancer and its comparison with healthy women.
Material & Methods: We used peripheral blood samples from 40 patients with sporadic breast cancer and 40 normal individuals. Analysis of the methylation statues of DBC2 promoter region was done by MSP (Methylation Specific PCR ) technique on the DNA extracted from the blood samples. The results were validated by sequencing. The methylation status was then correlated with the clinicopathological parameters of breast cancer patients.
Results:Methylation pattern was detected in 60% of the patients, whereas 25% of the normal individuals demonstrated a positive methylation pattern (P ≤ 0.01, odd ratio : 2.143). No significant correlation was obtained between methylated DBC2 and cliniclpathological parameters.
Discussion: Aberrant hypermethylation was observed preferentially in the patients. These findings along with the previous studies, propose that abnormal methylation pattern in DBC2 promoter region may be one of the main reasons for low expression of DBC2 in breast cancer and this hypermethylation pattern could play a fundamental role in the breast tumorigenesis.

Background and Objectives: Squamous cell carcinoma of the tongue (SCCOT) is the most common malignant neoplasm in oral cavity. At the time of the diagnosis of SCCOT regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. Although the level of healthcare has significantly improved, the survival rate is still low with an unsatisfactory cure rate. The present study was designed to establish a clinical review on adults with SCCOT and to determine whether the rate of SCCOT has been changed over the 20-year.
Methods: A cohort of 102 patients was recruited for this retrospective study. The study was carried out by reviewing the medical reports and case notes of patients with histologically confirmed SCCOT.
Results: The peak incidence was observed between 60 and 70 years. Stage I disease was found in 24, stage II in 64, stage III in 10 and stage IV in four patients. Seventy-three patients were treated with combined therapy; surgery and radiation, whereas, 29 patients received only surgery. The overall 5-year survival was 60%. Thirty patients developed tumor recurrence including 12 local, 12 nodal, four locoregional, and two distant. Thirty-four patients died during the follow-up period, six with persistent disease, and 62 remained cancer free, giving a mortality and morbidity rate of 39%.
Conclusion: This study recommends aggressive early treatment of patients with SCCOT including resection of the primary tumor with a safe margin (1.5cm) in addition to an appropriate neck dissection.

Background and Objectives: Laboratory reference values are an important tool for clinical management of patients. Reference values being used in most laboratories in Iran have been provided from the established reference values from developed countries. However, several variables can affect on these laboratory parameters. Therefore, this study was carried out to establish the reference values of hematological parameters in the blood donors of central province of Iran as a general population.
Methods: Blood samples of 1100 male blood donors were collected consecutively from Blood Transfusion Organization. Complete blood cell (CBC) count in 2012 and differential was performed using an automated hematology analyzer.
Results: The median and 95% reference values (2.5th-97.5th) for Hb and platelet counts were 15.5 g/dl (14.1-17.7) and 209 ×109 cells/L (151-322) respectively. The median for total WBC count, neutrophil, lymphocyte, monocyte and eosinophil were 6.7 ×109 cells/L (4.3-11.2), %58 (%50-%70), 40% (30-49%), 0% (0-2) and %1 (0-3%), respectively.
Conclusion: The hematological profile of the population in central province of Iran was different from the reports of other countries and also the standards reference ranges described in textbook. So, further nationwide study should be carried out to establish the hematological reference values of the Iranian population as a whole.

Background and Objectives: An increasing number of tularemia was reported in all over the world. This infection is characterized by different clinical syndromes that can be considered in differential diagnosis of infectious disease. Despite effective antibiotics against Francisella tularensis, this infection is still as one of the agent of mortality and disability among infectious disease.The aim of this study was investigation of seroepidemiological of F. tuleransis among children between 2-18 years old in a risky zone in Iran.
Methods: This cross-sectional, laboratory-based study in two distinct villages Saragha seyed and Khoye in Chaharmahal va bakhtiari Province involved 183 children, adolescents who had no sign and symptom of disease and were screened for tularemia immunoglobulins G (IgG), using the ELISA-based quantitative assay.
Results: In general, from 183 children 11 persons (6%) were seropositive, compared with 172 persons (94%) were seronegative.
Conclusion: According to the high prevalence of antibodies against F. tularensis in this study, this infection must be considered as differential diagnosis of infectious disease in suspect patients.

We present unusual retained remnants of hidden conjoined twin of possible abdominal pagus after 21 years who presented with abdomenpain and incidentally have found his forbidden conjoined twin. He presented for many years with a palpable epigastric mass, and recent abdominal pain, early satiety, nausea and vomiting. The mass was a like deformed fetus weighing 815 gr who was anencephalic and deprived of viscera but there was a distinct vascular connection through the rig limb. Microscopic examination revealed a normal epidermis with melanocytes overlying dermis with mature adnexa. The fetus plain film after surgery showed a rather complete skeletal system. All above findings were in favor of fetus in fetus, a rare congenital entity in which a nonviable parasitic fetus grows within the body of its twin.

Background and Objectives: Chicken pox has potential complications during pregnancy for both the mother and her baby. The aim of this study was to determine the Varicella-zoster virus (VZV) immune status in pregnant women in Babol and its surrounding neighborhoods.
Materials and Methods: This seroepidemiological study was carried out on 427 pregnant women referred to Rohani Hospital, Babol, northern Iran from 2010 to 2011. The immune status (IgG level) was determined using ELISA method and correlation with age, place of residence, history of VZV infection and the number of siblings were evaluated.
Results: The mean age of the subjects was 27.16 + 5.7 years and their mean antibody level was 103.552 + 63.37 U/ml. Out of 427 pregnant women studied, 8.7% were seronegative, 1.2% were equivocal and 90.2% were seropositive. There was no correlation between age, the place of residence (urban or rural) and titer of antibody. However, higher antibody titer was found in women with more siblings.
Conclusion: Considering 90.2% of pregnant women were VZV seropositive, evaluation of VZV antibody in order to prevent complications in non-immune pregnant women and vaccination for women with age less than 25 years old and no VZV infection history, prior to pregnancy is recommended.

Primitive neuroectodermal tumor (PENETs) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. In more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). Immunohistochemical staining may be required for diagnosis of PENET. The cells of tumor express CD99, vimentin, NSE, FL1 but do not express Ck, LCA, myogenin, and WT1. We present a 36-year –old female with left –side tender abdominal swelling, and history of trauma to abdominal. CT imaging confirmed a huge solid mass of kidney, also extending into renal pelvis. Histological section of the lesion showed a malignant proliferation of small round cells in rosette-like pattern with foci of necrosis area. Tumor cells expressed high level of CD 99 antigen. The diagnosis of the lesion was primitive neuroectodermal tumors (PNET). Following-up after 6 months showed no recurrence.

Background and Objective: Since it is essential for the research policy makers to acquire knowledge about the global ranks of their countries in in Pathology and Forensic Medicine subject areas, scientometrics experts have been always ranking and analyzing countries on the basis of ‘total number of papers’, ‘total number of citations’ and ‘citations per paper’, etc.
Materials and Methods: The data in SCImago[1] has been used to analyze and evaluate the global ranks of Iran, Turkey, Saudi Arabia, India, Pakistan, South Korea and South Africa. These countries had a similar growth trend in many indicators of science and technology in the past.
Results: This article mainly deals with the extent of presence of these countries in Pathology and Forensic Medicine subject areas, their international global ranks and comparing them with each other. Furthermore, data show that these countries had a different situation considering “citations per Document”; because it did not match with their “number of Document” and “total number of citations” to their papers and did not increase accordingly. “Citations per Document” is considered as one of the most important indicators which show the average number of citations to each document.
Conclusion: The situation of Iran under the study seemed to be better in some areas such as ‘Cite per Documents’ than their situation in other areas; however, this point should be taken into consideration that they did not have an equal presence in all areas.

Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago. Present and past medical history was not significant finding. Pathologic evaluation identified the cystic structure as unilocular hydatid cyst. Primary hydatid disease constitutes a potentially serious differential diagnosis of any subcutaneous mass in endemic area of hydatid disease.
