Abstract Background.—We have previously studied the immunoreactivity of 3 novel smooth muscle–specific proteins, α-smooth muscle actin, smooth muscle myosin heavy chains, and calponin, to assess myoepithelial differentiation in pleomorphic adenomas. Objective.—To further expand our knowledge of myoepithelial differentiation in other benign and malignant salivary gland tumors. Design.—Formalin-fixed paraffin sections of 135 salivary gland tumors with associated normal glands were stained with monoclonal antibodies using the avidin-biotin complex immunoperoxidase method and enzymatic and microwave heat–induced epitope retrieval. Results.—In adenoid cystic carcinomas and epithelial-myoepithelial carcinomas, all 3 markers exclusively highlighted the myoepithelial cell components and the epithelial cells were entirely negative. No immunostaining was detected in canalicular adenomas, oncocytomas, Warthin tumors, acinic cell carcinomas, mucoepidermoid carcinomas, squamous cell carcinomas, and polymorphous low-grade adenocarcinomas. Salivary duct carcinomas and adenocarcinomas, not otherwise specified had a distinctive pattern of uniform periductal staining of reactive myofibroblastic cells, and in salivary duct carcinomas some ducts retained a peripheral immunoreactive myoepithelial cell layer. Conclusion.—Immunoreactivity for these 3 smooth muscle–specific proteins confirms the known neoplastic myoepithelial component of adenoid cystic carcinomas and epithelial-myoepithelial carcinomas. The consistently positive staining pattern in adenoid cystic carcinomas may be diagnostically useful in discriminating histologically similar but consistently negative polymorphous low-grade adenocarcinomas. Periductal linear staining in adenocarcinoma, not otherwise specified and salivary duct carcinomas is distinctive and appears to represent a tight cuff of myofibroblasts associated with the infiltrating glands.

Background: Salivary gland tumors are rare, generally benign and affect both major and minor salivary glands.Objective: To find out the pattern of distribution of different benign and malignant salivary gland epithelial tumors and their relation to age and sex in a tertiary care center in Bangladesh.Methodology: This is a retrospective study. Details of epithelial salivary gland tumors were obtained from department of ENT, National institute of cancer & research hospital (NICRH), Dhaka, Bangladesh from the period January 2009 to December 2012 (3 years).Result: A total number of 261 cases presenting with both benign and malignant salivary gland tumors were analyzed according to gender, age and histopathological findings. There were 130 (49.84%) males and 131 (50.19%) females with the male female ration of 1: 0.99. Age of study population ranged from 10 to 70 years with the mean age 40.78. Percentage of benign salivary gland tumors was 73.94% and malignant salivary gland tumor 26.05%. Among major salivary gland tumors, no sublingual tumors were found and parotid gland tumors were the commonest. Whereas, among minor salivary gland tumors palatal minor salivary tumors were common.Conclusion: Parotid gland was the most common site of origin of both benign and malignant salivary gland tumors. Histopathologically, pleomorphic adenoma was the most common benign salivary gland tumor and mucoepidermoid carcinoma was the most frequent malignant neoplasm. Adenoid cystic carcinoma was common minor salivary gland tumor.Bangladesh Journal of Medical Science Vol.15(1) 2016 p.90-94
