Lipomas of the gasterointestinal Tract are relatively uncommon in clinical practice. Most cases are asymptomatic with small tumor size and do not need any special treatment but the large ones are known to cause symptoms such as abdominal pain, obstruction, intussusceptions, and bleeding. The majority (90%) of these lesions are submucosal with predominantly right sided with a slight preponderance in females. Recurrence or malignant transformation has not documented in these lesions. We present a case of giant submucosal lipoma in a 33 years old male in sigmoid colon presenting with abdominal pain and rectal bleeding from Imam Hospitals’ complex, Tehran-Iran. In patients with gastrointestinal symptoms and large mass in sigmoid and with non-specific findings in colonoscopy, this disease has to be taken into consideration.

Although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. Sarcomas represent less than 1% of primary breast neoplasms. These tumors are at high risk of recurrence and are known to have poor prognosis. Surgical resection is the primary treatment for these lesions and axillary lymph node dissection is not routinely indicated in the setting of a clinically negative axilla. In this report, we introduce a patient with breast stromal sarcoma based on surgical pathology that has experienced axillary lymph node recurrence later during follow up period.

Human echinococcosis remains a complex problem that affects several organs. Hydatid disease mainly (85%) affects liver as well as lung, and 10% the rest of the body. Renal involvement is about 2% while skin hydatidosis is nearly 1%. Coincidental involvement of kidney and skin is very rare. We report a 51 year-old female patient with renal and skin (chest wall) hydatid lesions that were excised radically and the diagnosis of hydatidosis was confirmed histologically in EMAM REZA Hospital, Tehran in 2007. For treatment albendazol 400 mg BID was chosen, followed by monthly inspection of liver and CBC control up to six months. The case did not show any sign of recurrence in 24 months of following up.

Background and Objective: Fine needle aspiration cytology (FNAC) is a well-established method of diagnosis in palpable masses of various sites. This study was conducted to evaluate the usefulness of FNAC as a diagnostic tool in the management of patients with cervical lymphadenopathy. Patients and Methods: Totally 178 patients admitted to Loghman-Hakim Hospital , Tehran, Iran, with cervical masses, were included in this study. They had undergone FNA and subsequently excisional biopsy of the same neck mass in which a lymphoid tissue lesion had been established. Results: Reactive lymphadenitis, metastatic neoplasm, Hodgkin’s lymphoma, and non-Hodgkin’s lymphoma constituted 59.6%, 17.9%, 14.6% and 7.8% of total cases, respectively. In 27 cases (15.2%), the FNA findings were nondiagnostic. Diagnostic accuracy of FNAC was about 88%. Sensitivity, specificity, positive and negative predictive values were 75.8%, 96.6%, 94% and 85.1%, respectively. Conclusion: FNAC has a high accuracy in the diagnosis of malignancies of cervical lymph nodes, but due to the existance of false negative cases, the benign results should be further evaluated if high clinical suspicion of malignancy exists.

In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-year-old female who presented with a firm, non-mobile thyroid nodule of the left lobe. Fine needle aspiration was performed, demonstrating fragments of fibrous tissue and few inflammatory cells including neutrophils and lymphocytes, findings that could be representative of Riedel’s thyroiditis. Frozen section examination during subsequent surgery and later histopathologic study confirmed the diagnosis. Fine needle aspiration of the thyroid, if successfully done, could be highly suggestive for Riedel’s thyroiditis.

Primary fallopian tube carcinoma is a rare tumor that histologically and clinically resembles epithelial ovarian cancer. Here we introduce a case of tubal carcinoma in a postmenopausal woman. The diagnosis of primary fallopian tube carcinoma is rarely considered preoperatively and is usually first appreciated by the pathologist. Because of low frequency of tubal carcinoma, there are few systemic pathological reports of its mode and extent of spread. Surgical staging and management as the use of chemotherapy follow the concepts used in epithelial ovarian cancer. In contrast to epithelial ovarian cancer, it is the importance of early lymphatic spread in this disease. The earlier diagnosis of primary fallopian tube carcinoma leads to an apparent better survival compared with its ovarian counterpart. However, as with epithelial ovarian carcinoma, stage and residual tumor are the most important prognostic variables. Only with more extensive clinical researches, ovarian carcinoma management principles should be used in clinical practice of this tumor.

Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral soft tissue, was seen and incompletely resected. Histologic examination exhibited a hypercellular,necrotic and mitotically active spindle-celled tumor with fascicular arrangement. Immunohistochemistry showed a positive reaction to SMA in tumoral cells. The patient was advised to refer for postoperative chemotherapy, which was rejected. One year later, the patient was brought to hospital with tumor recurrence. Chemotherapy was initiated for the patient immediately, but the patient was expired 3 days later.

Background and Objective: Ischemic heart disease (IHD) following atherosclerosis is the most common cause of cardiac deaths world wide. We aimed to investigate the pathologic features of atherosclerosis in non cardiac death cases to have an estimate of atherosclerosis prevalence in Mashad (North east of Iran). Patients and Methods : This descriptive (cross sectional) study was done, during October 2007 – March 2008, on 80 cadavers from 11 to 50 years old who had died of non cardiac causes and had no history of cardiac disease. After autopsy in forensic medical center, coronary arteries were removed and examined for atherosclerotic plaques. In case of a definite or suspicious lesion, microscopic slides were also prepared. Otherwise, three random slides from each branch of coronary arteries were studied by a pathologist. Results: We found that 73.1% of men and 61.5% of women had at least one fibrofatty or advanced plaque in major coronary arteries. Atherosclerosis in 41.8% of men and 30.8% of women was in advanced form. Frequency of advanced atherosclerotic plaques progressed with age reaching a maximum of 78.5% by the age of 41-50 years. In addition, prevalence of plaques suddenly increased after second decade of life. Atherosclerotic plaques were most commonly found in left anterior descending artery (60%) followed by right coronary (50%) and left circumflex (42.5%) arteries. Conclusion: This study showed an unexpectedly high prevalence of atherosclerosis in this population. It highlights the importance of cardiovascular risk factor screening from early ages of third decade.

Background and Objective: Microscopic evaluation of cervicovaginal smears (Pap smear) plays an essential role in detection of preneoplastic and neoplastic lesions of uterine cervix. A wide spectrum of changes is seen in Pap smears. Interpretation of intermediate changes which resulting in observation of so- called ASCUS is difficult. ASCUS is defined as a cellular change that is more marked than typical reactive change but lack features diagnostic of intraepithelial neoplasia. The aim of this study was determination of reliable cytological parameters to identifying real nature of ASCUS. Patients and Methods: In this descriptive, cross sectional study, all Pap smears with presence of ASCUS, which followed by biopsy samples in Urmia, ShahidMatahari hospital during March 1999 to December 2002 were reviewed. In this regard, 17 parameters of cytoplasm, nuclei and smear background were considered and data were analyzed by SPSS and Chi Square test. Results: Four parameters of irregular nuclear contour, increased nucleo- cytoplasmic ratio, cytoplasmic vacuolization and dirty background are highly suggestive of dysplasia. Conclusion: It is important to consider that to find out the real nature of ASCUS a group of parameters are more helpful than a single one. In addition, a single Pap smear is not enough for this purpose and further investigationis required.

Background and Objective: Approximately 45% of benign peripheral nerve sheath tumors (PNST) occur in head and neck regions. Malignant peripheral nerve sheath tumors (MPNST) are less common and only 8-15% of these tumors occur in head and neck region. In this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family history of these tumors in head and neck regions. Patients and Methods: In a cross sectional and retrospective study, we analyzed head and neck peripheral nerve sheath tumors in patients who referred to Amir-Aalam Hospital affiliated to Tehran University of Medical Sciences for 10 years (1996 to 2005). Results: There were 113 cases with a kind of nerve sheath tumor; the female/male ratio was 1.09. The frequency of schwannoma, neurofibroma and MPNST was 66.37%, 30.1% and 3.53%, respectively including 39 cases of acoustic neuroma, 18 cases of cervical nerve trunk involvement, 12 cases of facial nerve involvement, 11 cases of the 10th cranial nerve PNST and only one case of cervical sympathetic nerve involvement. Conclusion: Schwannomas are the most common types of PNSTs seen in head and neck regions, and aucoustic neuroma comprises the majority of them. About 25- 45% of extracranial schwannomas also occur in head and neck regions that usually present a slow growing of the mass lesion and various mass effects. Although neurofibroma and MPNSTs are less common, they must be kept in mind as differential diagnoses of other benign and malignant lesions in this region.

Background: and Objectives: Salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. Infections with multidrug resistant (MDR) strains of Salmonella have been associated with treatment failures. Salmonella spp. resistant to extended spectrum cephalosporins are increasing in prevalence worldwide. The aim of this study was to determine the antimicrobial susceptibility, multidrug resistance and extended spectrum beta lactamase (ESBL) production among clinical isolates of Salmonella spp. during 2007 in Tehran, Iran. Patients and Methods: In this cross-sectional study, fifty Salmonella spp. were identified by API 20E system and serotyped by the slide agglutination test. Disk diffusion test was performed. Double disk synergy test was used as a screening test for ESBL production, using disks of cefotaxime and ceftazidime with and without clavulanic acid. Results: From 50 Salmonella spp. 12 (24%) were S. enterica serotype paratyphi B, 24 (48%) S. enterica serotype paratyphi C and 14 (28%) were S. enterica serotype Typhi. The most susceptibility and resistance were observed to ceftazidime (98%) and amoxicillin-clavulanic acid (96%), respectively. 28(56%) were resistant to 5 or more antibiotics. ESBL production was detected by double disk synergy test in one isolate (2%). Conclusion: Results showed increase in antibiotic and multidrug resistance pattern of Salmonella spp. comparing to previous studies in Iran and other countries.It seems that this is the first report of Salmonella spp. ESBL producing in Iran.

Human brucellosis is common in developing countries and is a multi-system disease with a broad spectrum of clinical manifestations. Cutaneous lesions associated with brucellosis have been rarely reported in the literature. Here we present a case of a 32-year-old man with history of consumption of cheese made from raw milk seen with occurrence of pancytopenia and diffuse maculopapular rash during the course of Brucella infection. Physical examination showed fever, splenomegaly, mild hepatomegaly and pruritic maculopapular exanthema over the trunk, arms and legs. Laboratory tests revealed pancytopenia. Parasitic examinations and serologic tests for syphilis, salmonellosis, rickettsiasis, toxoplasmosis, Epstein-Barr virus, human immunodeficiency virus, and hepatitis B and C viruses were negative. There was no history of drug consumption.The Brucella agglutination test titer was 1/1280 and histological examination of skin biopsy showed lymphohistiocytic perivascular infiltrates in the upper dermis.Lesions were interpreted as Brucellar dermatitis , The patient was subsequently treated with oral doxycycline and rifampin and was discharged in good health. If there is suspicion of exposure to infected food products, brucellosis should be included in the differential diagnosis of pancytopenia in Brucella-endemic areas; there may be skin lesions other than purpura that can accompany thrombocytopenia.

Background and Objective: Bacterial meningitis is an important cause of mortality and long-term neural morbidity. Immediate diagnosis and treatment are necessary in appropriate time. This study was designed in Afzalipour Hospital in Kerman to evaluate meningitis causes, frequency and CSF laboratory changes. Patients and Methods: In this retrograde descriptive study from September 2003 to September 2005, documents of all the hospitalized patients with diagnosed meningitis in Afzalipour Hospital of Kerman, southeast of Iran were studied. Findings: During this period, 126 patients were hospitalized . The age average was 15.2 ± 5.2 yr. Males were more than females (69% vs 31%) & 64% were children.Majority of patients were admitted in winter (42.9%) followed by spring (31%) . 9.5% had viral meningitis . 89.5% of patients with bacterial meningitis had negative CSF culture . Positive culture included 6 cases of haemophilus influenzae type B , 3 cases of pneumococcal and 3 cases of meningococcal. Average level of glucose in CSF in positive culture group was less than negative culture group (22.5mg/dl vs 53.5mg/dl) . All positive culture patients had pro>100mg/dl and WBC>1000/mm3. Conclusion: 10.5% of patients had positive culture, which might suggest that there were some errors in microbial cultures done in this hospital. More prevalence of meningitis in children was similar to other studies. The most common cause was haemophilus influenzae , so Iranian children vaccination should be considered.

Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the only marker of HBV infection in high risk patients. Patients and Methods: In this cross-sectional study, 395 patients including 289 patients on chronic hemodialysis (HD) and 106 HIV infected subjects were enrolled. HBsAg, anti-HBs, anti-HBc, Hepatitis C antibody (anti-HCV) and Alanine aminotransferase (ALT) levels were tested in all subjects. The presence of HBV-DNA was determined quantitatively in plasma samples of patients with isolated anti-HBc by real-time PCR. Results: Of 395 patients, 40 (10.13%, 95% CI, 7.1%-13.1%) had isolated anti-HBc. HBV-DNA was detectable in 12 of 40 patients (30%, 95% CI, 15.8%-44.2%) who had isolated anti-HBc. Conclusion: Our study showed that detection of isolated anti-HBc could reflect unrecognized HBV infection; hence, screening of these patients is useful to preventing of HBV transmission.

Littoral cell angioma is a splenic vascular tumor of splenic sinus lining cells that is considered benign in general. This report describes a case of littoral cell angioma with no malignant histological features. The lesion is composed of anastomosing vascular channels resembling splenic sinus; they are lined by endothelial cells which show mitotic activity very rare. Immunohistochemically, the tumor cells were positive for both endothelial (Factor VIII-AG, CD34) and histiocytic markers (KP1 or CD68). The morphologic and immunohistochemical findings in this tumor confirm the presence of dual (endothelial / histiocytic) characteristics of the reticuloendothelial cells lining the splenic sinus, justifying the term littoral cell angioma.

Chronic granulomatous disease (CGD) is a rare inherited disorder characterized by inability of phagocytes to generate oxygen radicals needed for intracellular killing of phagocytic microorganisms. We report a 2.5-year-old Iranian female with multiple liver abscesses. She was admitted in surgical ward because of abdominal pain and fever for one month duration that had no response to conventional antibiotic treatment. The results of laboratory tests were: WBC=17000, Neutrophils=82%, lymph=17%, ESR=100. Other tests except nitroblue tetrazolium (NBT) and dihydrorhodamine (DHR) tests were negative and according to these two tests the final diagnosis was CGD. Supportive care along with recombinant interferon γ and oral trimethoprim-sulfamethoxazole for prophylaxis of infections started. Now after 18 months she is alive and healthy. Any patient with recurrent or unusual lymphadenitis, hepatic abscesses, osteomyelitis at multiple sites, a family history of recurrent infections, or unusual infections with catalase positive organisms, like S. aureus, requires evaluation for CGD.

Background and Objectives: Cardiovascular disease is the most common cause of death in developed countries. In addition to traditional risk factors for cardiovascular disease, nowadays, accumulating evidence indicates that a variety of infections contribute to pathogenesis of atherosclerosis, (We investigated whether Helicobacter pylori infection is related to Prevalence of coronary heart disease) there is controversy concerning the impact of H. pylori infections in atherosclerosis. Materials and Methods: This case-control study was carried out on 130 subjects who underwent coronary angiography in the School of Medicine, Tehran University of Medical Sciences, Iran, from Oct 2006 to Oct 2007. According to angiography findings, the patients were grouped into cases (n=70) with Coronary Artery Disease (CAD), and normal control group (n=60). Then, using ELISA method, specific anti H. pylori IgGs were measured in all subjects. The connection between CAD and H. pylori infection was studied. Results: Among the 130 patients, anti-H. pylori IgGs were detected in 80% of cases and 65% of control subjects (p=0.05). The investigation shows that CAD correlated significantly with hypertension, diabetes, and smoking (p<0.05) although there was no associations between these traditional risk factors, and H. pylori infection. Conclusion: These findings raise the possibility that exposure to H. pylori may lead to an increased risk of coronary artery disease independent of other risk factors.

Background and Objectives: Preterm labor is a serious problem in obstetrics, accounting for 70% of perinatal mortality. High sensitive C - reactive protein (HS-CRP) is a sensitive marker of Inflammation. Our aim in this study was to determine Amniotic fluid hs-CRP concentration and its correlation with pre-Term delivery. Materials and methods: This prospective study was conducted on 90 pregnant women who underwent genetic amniocentesis between the 15th and 20th weeks of gestation. All patients were followed until delivery. Pateints with abnormal karyotype and iatrogenic preterm delivery for fetal and maternal indications were excluded. The samples were carried immediately to the laboratory of Imam Khomaini Hospital Complex, Tehran, Iran for cytogenetic examination and tested for HS-CRP by turbidimetric method. Non parametric tests and receiver-operating characteristics curve analysis were used for statistical purpose. Results: The study showed no correlation between amniotic fluid HS-CRP concentrations with preterm delivery. Maternal serum alpha-fetoprotein (AFP) levels were higher in patients delivered preterm compared with term deliveries (P=0.036). Conclusion: Our results implicated that HS-CRP like other acute phase response markers was not as a possible risk marker of preterm delivery.

Background and Objectives: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant cancer predisposition syndrome caused by germ-line mutations in DNA mismatch repair genes. Tumors arising as a result of these mutations display instability in a sequence area known as microsatellites. Studies have shown that some Bethesda markers (BAT25, BAT26) are more efficient than others in identifying Microsatellite Instability (MSI) in tumors of HNPCC patients. The aim of this study was toevaluate the possible benefits of two MSI markers BAT25 and BAT26 to identifying microsatellite instability in tumor tissues from HNPCC patients. Material & Methods: We used 49 cases gathered from north-east Iran. Microsatellite Instability analysis was performed using fluorescent-labeled primers. Statistical analysis was achieved using SPSS software. Results: 24/5% (12/49) and 34.7% (17/49) of the cases showed MSI in BAT25 and BAT26, respectively. None of tumor sample was MSI positive for both markers. Discussion: MSI frequency is considerably lower, compared to other findings. This might be due to the fact that environment and Race has great influence on MSI frequency.

ABSTRACT Background and Objective: There have been concerns over possible association between mercury and neurodevelopmental outcomes in infants. In this study we aimed to determine whether blood levels of mercury are above safe values in Iranian infants or not. Materials and Methods: A total of 85 infants (0, 2, 4 and 6 months old) were enrolled in this study. All of them received vaccines according to Iranian immunization schedules. We measured total mercury in all blood samples by cold vapor atomic absorption. Results: The mean concentration of blood mercury in our subjects were as follows: newborns as 33.95 ± 11.86 nmol/l (with a range of 23.93-52.84), 2 months as 32.94 ± 11.76 nmol/l (with a range of 23.92-52.84), 4 months as 30.44 ± 10.44 nmol/l (with a range of 23.92-50.85) and 6 months as 37.93 ± 12.97 nmol/l (with a range of 21.43-52.34). There was not any significant difference for the mean concentration of blood mercury in those age groups. The lowest level of blood mercury detected was 21.43 nmol/l and the highest level was 52.84 nmol/l. Conclusion: The finding of this study showed that approximately 33% of the infants had blood mercury levels above the U.S. Environmental Protection Agency recommended reference dose of 5.8 μg/l (29 nmol/l). Therefore, it is needed to reduce exposure of infants to mercury from all sources including thimerosal containing vaccines (TCVs) in Iran.
