FNAC and Histopathology of Salivary Gland Tumors

Abstract

Accounting for less than 2% of all human neoplasm, salivary gland tumours are relatively uncommon. This is a retrospective study of all salivary gland tumor biopsies received at our referral teaching hospital in Ahmadabad from January 2007 to October 2008. It will be noted that the most common benign neoplastic lesion during the present study as pleomorphic adenoma in the age group of 3nd decade of life (28 cases) followed by 4th decade (20 cases) Malignant lesions are common in age group of 5th decade of life (8 cases) Graphical presentation showing number of benign and malignant cases with their age distribution. Out of 100 cases, histopathological correlation was done in 60 cases. Most of the patients presented between 3rd and 5th decade of life. Males were predominantly affected with Male: Female ratio was 1:04. The commonest benign lesion was pleomorphic adenoma (74%) and the commonest malignant lesion was mucoepidemoid carcinoma (6%), In the present study, the incidence of benign and malignant lesion was 83% and 17% respectively. In the present study, FNAC had 100% accuracy rate for malignant lesion false negative result was obtained in 2(3.33%) cases. Thus, FNAC, in comparison to other methods of biopsy, is readily available, no anaesthesia is required, is a short procedure, reports are rapidly in one or two hours. It is cheap and cost effective, is an O.P.D. Procedure, least traumatic and has 100% patient compliance. It is highly reliable and accurate in expert hands.
