Background & Objective: Cell population and turnover are controlled by a balance between cell proliferation and apoptosis. Detection of apoptosis in oral cancer contributes to its better prognosis and improved management. This study aimed to quantify apoptotic cells in leukoplakia and oral squamous cell carcinoma (OSCC) using methyl green-pyronin (MGP) and hematoxylin and eosin (H & E) staining. Methods: The sample included a total of 130 subjects (comprising 108 males and 22 females). Formalin fixed and paraffin embedded tissues were used and categorized into three groups of normal oral mucosa (n=10), leukoplakia with dysplasia (n=60), and OSCC (n=60). The number of apoptotic cells and apoptotic index (AI) were calculated after staining with MGP and routine H & E stained slides. Results: MGP stained the condensed chromatin of apoptotic cells. Statistically significant difference (P≤0.001) was observed among various study groups in terms of numbers of AI and apoptotic cells. Also, AI increased with increasing grades of dysplasia, and it was the highest in well differentiated OSCC. Results were statistically significant in both H & E and MGP stained sections (P≤0.001). A good correlation was found between MGP and H & E staining results. Conclusion: MGP is more specific and can lead to intense staining for chromatin in apoptotic cells. Accordingly, it can provide a good alternative to H&E in identifying apoptotic cells.

Background & Objective: Micronucleus assay of buccal mucosa cells is a simple bio- monitoring method for diagnosing the genetic damages of toxic agents. The aim was to study the genotoxic effect of waterpipe smoking on buccal mucosa cells using micronucleus assay. Methods: This was a case control. A total of 30 male waterpipe smokers and 30 non-smokers were included in the study. The exfoliated buccal mucosa cells were scrapped using wooden spatula and were spread over glass slides. The mean number of micronuclei was determined using Feulgen-stained slides. The number of micronuclei per 1000 cells was calculated and compared between the two groups of smokers and non-smokers. Result: The mean number of micronuclei in waterpipe smokers and non-smokers was 1.94±0.39 and 1.68±0.35, respectively. The micronuclei count in waterpipe smokers was significantly higher than non-smokers (P=0). The difference between the number of waterpipe smoking and micronuclei count was significantly different (P=0). Conclusion: The mean number of micronuclei in buccal mucosa cells of waterpipe smokers was significantly higher than non-smokers. The genotoxicity effect of waterpipe was dose-dependent.

Desmoplastic fibroma (DF) is a benign, locally aggressive neoplasm that rarely occurs in the facial skeleton. It usually presents during the first three decades of life. Due to its aggressiveness and high recurrence rate, early diagnosis is imperative, and complete surgical removal of the lesion is the treatment of choice. Herein, we present three cases of DF namely a 2 year-old girl with a mandibular DF, a 9 year-old boy with a maxillary lesion and a 1.5-year old boy with a mandibular DF. Complete clinicopathological information, treatment plan and long-term follow-up of patients are discussed. Histopathologic features of 3 cases revealed non-capsulated spindle cell tumor with fascicular or swirling patterns in incisional biopsy. Immunohistochemical staining was performed to make a definitive diagnosis. Strongly positive nuclear immunoreactivity for β-catenin confirmed the diagnosis of desmoplastic fibroma in 3 cases. Segmental mandibulectomy, partial maxillectomy and hemimandibulectomy were done for the cases. There was no recurrence in our reported cases after 8 and 11 months and 3 years follow up, respectively. It is noteworthy that despite the aggressive nature of DF, young patients often respond well to wide resection treatment.

Epithelial-myoepithelial carcinoma (EMC) is considered as a rare malignant salivary gland neoplasm with good prognosis, low recurrence rate and rare metastasis. Here we present a case of epithelial-myoepithelial carcinoma in a 42-year-old female with a swelling of 3-year duration in her palate. Histopathologic evaluation of the lesion demonstrated a well-circumscribed, biphasic salivary gland tumor composed of double-layered ductal/glandular structures, composed of small luminal eosinophilic cells and abluminal larger clear myoepithelial cells, and luminal cells were positive for pan-cytokeratin, while the abluminal cells exhibited strong immunoreactivity for p63. Ki-67 proliferative index was 1% in abluminal cells. In this article, histopathologic and immunohistochemical features of EMC and its mimics are discussed and the previously reported cases of EMC in the literature are summarized.

Background and Objective: This study was aimed to evaluate the collagen fibers qualitatively and its correlation with microvascular density in various grades of oral submucous fibrosis (OSMF). Material and Methods: The present study comprised of total 40 cases of oral submucous fibrosis. Picrosirius red staining was done on all the specimens’ sections. They were analyzed for the colour and orientation of collagen fibers. Morphometric measurements were done using image analysis on immunohistochemical stained sections for Factor VIII-related antigen and analyzed for microvascular density. Results: Picrosirius red polarizing microscopy results revealed that there was a shift in the colour of collagen fibers from greenish yellow to orange red and red colour as the severity of the oral submucous fibrosis increased. The collagen fibers showed mixed orientation in early oral submucous fibrosis and parallel orientation in advanced oral submucous fibrosis. There was a significant decrease in microvascular density from early to advanced oral submucous fibrosis. Conclusion: The change in the colours and orientation of collagen fibers in early and advanced oral submucous fibrosis could be attributed to the fibre thickness, type of collagen, alignment and packing, cross-linking of the fibers and the section thickness. However, in advanced cases the vascularity is reduced which may predispose to epithelial atrophy and subsequent malignant changes.

Background and objective: Fine needle aspiration cytology (FNAC) of salivary gland lesions is an accepted and useful diagnostic tool to differentiate between benign and malignant lesions. Majority of the neoplasms are benign, and specific diagnosis on cytology can be made in most of the cases. However, the utility is limited by the overlapping and heterogeneous morphological features of benign and malignant neoplasms. The current study aimed at investigating the cytomorphological features of salivary gland lesions with histopathological correlation and performing risk based stratification of these lesions using the recommended Milan system for reporting of salivary gland cytopathology (MSRSGC). Methods: The current study was conducted on 192 retrospective and prospective cases of salivary gland lesions over a period of three years from October 2014 to September 2017. Cytohistopathological correlation was observed in 62 cases. Subsequently, cytomorphological features were further revaluated, classified according to MSRSGC into six groups, and correlated with clinico-histopathological features. Result: Diagnostic sensitivity and specificity of FNAC for salivary gland lesions was 63.16% and 97.62%, respectively. The positive predictive value was 92.31% and negative predictive value was 85.42%. The diagnostic accuracy to differentiate between benign and malignant lesions was 86.88%.The number of cases in each diagnostic category and the risk of malignancy (ROM) were as follows: nondiagnostic – three cases (ROM – 33.33%), nonneoplastic – 14 cases (ROM – 7.14%), atypical – one case (ROM – 100%), benign – 28 cases (ROM – 7.14%), NUMP – one case (ROM – 100%), suspicious – one case (ROM -100%), and malignant – 13 cases (ROM – 92.30%). Conclusion: Risk based stratification scheme as recommended by MSRSGC can provide a standard method to analyse the results and help to plan the management of salivary gland lesions.

Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas. These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis. Biopsies have been the gold standard for the diagnosis of such lesions. This study reports on an acute presentation of giant peripheral ossifying fibroma, clinically mimicking a malignant lesion due to its atypical presentation along with its characteristic histological features, which led to the establishment of the diagnosis.

Background and objective:Gingival bleeding reduction in smokers has been associated with decreased blood vessel density. The mechanism of suppressive effect of cigarette smoking on blood vessel density is not precisely defined. The aim of this study was to evaluate the impact of smoking on angiogenesis by assessing mast cells density and VEGF expression in chronic periodontitis. Materials& Methods: 52 paraffin embedded block of gingiva tissues with periodontitis obtained from 30 nonsmokers and 22 smokers undergoing flap surgery were examined immunohistochemically for VEGF expression. Mast cell counts was completed on toluidine blue stained slides. Exposure to cigarette smoking was calculated by the number of packs × year. Patients were classified into 4 groups based on the number of smoked cigarettes. The correlation between VEGF expression and mast cell counts was evaluated and compared in nonsmokers and smokers. Results: The mean number of mast cells (p=0.004) and average value of VEGF expression (p = 0.000) in nonsmokers was significantly higher than smokers. No correlation was noted between VEGF expression / mast cell counts and number of smoked cigarettes in four groups of smokers (p=0.29,0.12 , 0.20 and 0.11, respectively). Conclusion: Mast cells and VEGF expression may account for suppressive effect of cigarette smoking on blood vessels in periodontitis.

Background and objective:Candida albicans (C. albicans) play a significant role in oral mucosal carcinogenesis. It can be identified using various techniques in cytological smears. But, very few studies have been conducted on histopathological sections using calcofluor white M2R under fluorescent microscopy. Additionally, detection and quantification of Candida colonies and its correlation with various grades of oral leukoplakia and oral carcinomas have not been explored much. Methods:The current retrospective study included 80 samples from archives consisting of 60 samples in the study group (10 cases each of mild, moderate, and severe epithelial dysplasia (totally 30) and 30 cases of oral carcinoma). Sections were stained with calcofluor white (CFW) and 10% KOH for the observation under fluorescent microscopy and correlated with different grades of oral leukoplakia and oral carcinomas. Chi-square test was used in SSPS software to study the presence and absence of Candida sp. in different groups. Results:The study groups of oral carcinoma and dysplasia showed a significant association with Candida sp. (P=0). When carcinoma was compared with each grade of dysplasia, except mild dysplasia (P=4.4E-05), both moderate (P=0.402195) and severe dysplasia (P=0.558746) showed an insignificant P-value. When the groups of mild (13.3%), moderate (30%), and severe (33.3%) dysplasia were considered independently, the incidence of Candida sp. increased as the grade of dysplasia increased. The number of colonies have been counted and the maximum number of colonies have been observed in carcinoma and the least have been observed in mild dysplasia. Conclusion: A significant association of Candida colonies with epithelial dysplasia and oral cancer was established. Further, CFW was found a promising candidate to identify Candida colonies in tissue sections using fluorescent microscopy.

Gorham’s disease is a rare and atypical disorder epitomized by progressive osteolysis of bone with eventual total disappearance of bone. The etiology is poorly understood with variable clinical presentation. Most times it is initially misdiagnosed as temporomandibular joint dysfunction, periodontal disease or odontogenic tumors clinically and radiographically in routine dental practice. Radiographic examination, such as Cone Beam Computerized Tomography (CBCT) play a vital role in diagnosing such disorder resulting in disappearance of the involved bone entirely, which is a definitive distinguishing feature of this condition. Regarding the rarity of the condition, the current study presents a case of Gorham’s disease with distinctive clinical, radiological, and histological, features involving maxilla and mandible.

Background & objective: Changes in submucosal vascularization and inflammation, determined by immunohistochemistry staining, were shown to be correlated with the development of dysplasia and invasiveness of epithelial cells in premalignant and malignant lesions. This study evaluated changes in sections routinely stained with Hematoxylin and Eosin (H&E) in order to investigate vascular density and intensity of inflammatory cells infiltration during the progression of oral leukoplakia with mild dysplasia to Squamous Cell Carcinoma (SCC).The aim of the research was to determine whether changes in sub-mucosal vascularity and inflammatory infiltration of leukoplakia in routine H&E-stained sections could contribute to the assessment of severity of the lesion. Methods: In this cross-sectional, comparative and descriptive study, vascular density and inflammation intensity of 125 available samples of H&E-stained sections, consisting of 35 cases of mild and moderate dysplasia, 38 severe dysplasia and carcinoma in situ, and 52 SCC, were investigated. To analyze the data, chi-square test, Mann-Whitney test, Kruskal-Wallis test, Tukey’s post hoc test, and cumulative ordinal logistic regression were conducted. Results: There was a significantly higher vascular density in cases with severe dysplasia, in situ carcinoma, and SCC compared to those with mild to moderate dysplasia (P<0.0001). However, the difference in vascularity was not statically significant between severe dysplasia, carcinoma in situ, and SCC (P=0.78). Intensity of inflammatory cells infiltration in the underlying connective tissue was significantly different among the three groups (P<0.0001), and the highest intensity of inflammatory cells infiltration was seen in the SCC group. Conclusions: Increased submucosal vascularization and inflammatory cells infiltration can contribute further to predicting more aggressive epithelial dysplasia.

The solitary fibrous tumors (SFT) are rare tumors in the head and neck region and there have been only 5 cases reported in the literature in the soft palate. The current paper presents a unique case of a 62-year-old male with TFS arising in the soft palate. The tumor was highly cellular, composed of bland looking haphazardly arranged spindle cells. The signal transducer and activator of transcription (STAT)-6 and nuclear β-catenin were reactive by immunohistochemistry (IHC). The current case highlights the importance of the STAT-6 and the β-catenin as IHC markers to make a differential diagnosis with other entities. In summary, the paper presents the first reported case of a SFT of the soft palate in a male patient with nuclear expression of STAT-6 and β-catenin.

Osteoid osteoma (OO) is a benign osteogenic lesion that is extremely rare in jaws. It is characterized by proliferation of either cancellous or compact bone and can be central, peripheral or extraskeletal. Pain is a distinctive feature of this lesion accompanied by vasomotor disturbances, which occur long before radiographic and histopathology findings manifest. Here, we present a rare case report of OO of maxilla in a 40-yr-old male patient with noteworthy clinical, radiological and histological presentation. The diagnosis of OO is usually obtained by radiographs confirmed by histopathological analysis. Thus, the oral physician should have keen observation and appropriate knowledge concerning the same to avoid confusion with similar bony lesions.

Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing odontogenic epithelium. The lesion has a slow growth along with cortical expansion with equal predilection in the anterior maxilla and posterior mandible. Radiologically, multilocular radiolucency is the most frequent finding with few cases being associated with root resorption or displacement. Microscopically, mature collagen fibers and numerous fibroblasts along with odontogenic epithelial islands are characteristically found. Central Odontogenic Fibroma responds well to surgical enucleation with no tendency for malignancy or recurrence. Here we report a rare case report of an 18 yr old male patient with Odontogenic fibroma of the posterior maxilla.

Background: In cancers of prostate, breast, oropharynx, lung, hypopharynx and skin, human tissue kallikreins has been demonstrated as a main role in these problems. There are many research works in which some human tissue kallikreins are expressed in salivary glands. In the present study, the main goal was to determine expression of human tissue kallikreins 4, 8, 10, 11 and 13 in pleomorphic adenomas and mucoepidermoid carcinomas. Methods: Sixty-six specimens (45 cases of pleomorphic adenomas and 21 cases mucoepidermoid carcinomas) were selected for final analysis by immunohistochemistry. For doing association test, clinical parameters obtained from the patients’ medical charts, which included age, gender were used and the nonparametric tests employed for statistical analyses. Results: The expression of human kallikreins 4, 8, 11 and 13 was more prominent in benign and malignant tumors compared to that in normal tissues and the difference was significant. In addition, the expression of human kallikreins 4, 8, 10 and 11 in malignant tumors was more than that in benign tumors, with statistically significant differences. Conclusion: The differences in the levels of human kallikreins 4, 8, 11 and 13 suggest that kallikreins may benefit in determining tumor behavior of salivary gland tumors.

Central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra-gnathic incidence is rare.Multifocal CGCGs of the jaws are very rare and suggestive of systemic diseases such as hyperparathyroidism,an inherited syndrome such as Noonan-like multiple giant cell lesion syndrome or other disorders.Very few cases of multifocal CGCGs in the jaws without any concomitant systemic disease have been reported. This paper describes an unusual case reported to the Oral Surgery Department of Dr. D.Y.Patil Dental College & Hospital, Nerul, Navi-Mumbai in 2014ina45-year-old male with multifocal central giant cell granuloma involving maxilla and mandible. The serum alkaline phosphatase, calcium and phosphorus levels were within the normal limits. After complete clinical examination hyperparathyroidism and clinical characteristic of any syndromes such as Noonan-like syndrome and neurofibromatosis were ruled out. Thus this paper reports a non-syndromic multifocal central giant cell granuloma.

Neurilemmomas are benign tumors of peripheral nerve sheath Schwann cells. One of the variants of neurilemmoma is the ancient type of neurilemmoma characterized by degenerative features such as cystic degeneration, calcification, hemorrhage and hyalinization which could be easily misdiagnosed. Their occurrence in oral cavity is extremely rare and intraosseous type occurring in maxilla is exceedingly rare with very few cases being published in literature. A 38 year old male patient reported with a chief complaint of swelling over the left cheek and left upper back region since 10 months. The case is of recurrent intraosseous ancient neurilemmoma in the maxilla in the patient which is distinctive for the lesion. This unique case presented with distinct histologic architectural pattern of ancient neurilemmoma showing degenerative changes such as cystic degeneration and recurred within a short duration of time.

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.
