Histopathological Spectrum of Salivary Gland Tumors: A 10 Year Experience

This study was carried out to study the histopathological spectrum of salivary gland tumors and to know their pattern of distribution. A combination study was done with retrospective data of eight years from june 2001 to may 2009 and prospective data of two years from June 2009 to June 2011 in the department of pathology of our hospital. The study was duly approved by Hospital Ethical Committee. Out of total 80 cases, 49(61.25%) were benign and 31(38.75%) were malignant. Predominance of males was observed with M: F ratio of 2.3:1. The mean age observed was 44.76 years with age range of 12 to 75 years. Benign tumors outnumbered the malignant ones. Parotid was the most common site for the location of tumors (65%) followed by submandibular (25%) and minor salivary glands (10%). Pleomorphic adenoma was the commonest salivary gland tumor observed in both sexes. Mucoepidermoid carcinoma was the most common among the malignant salivary gland tumors followed by adenoid cystic carcinoma. In conclusion, the mean age of all salivary gland tumors was 44.76 years and age range was 12-75 years with male predominance. Benign tumors outnumbered the malignant ones with parotid gland being the most common site and pleomorphic adenoma being the commonest subtype.
