CLINICO PATHOLOGICAL STUDY OF TUMOURS OF PAROTID GLAND IN TERTIARY CARE HOSPITAL , PENCHIKALAPADU, KURNOOL

Abstract

purpose: The objective of the study was to study age and sex pattern in parotid gland tumors, and determine the accuracy of ne needle aspiration cytology in diagnosing parotid gland tumors, and also analyze different modes of surgeries for parotid gland tumors. Detailed study of thirty cases of parotid gland tumors admitted to viswabharathi medical college, penchikalapadu,Design: Kurnool from January -2021 to January 2022, Out of 30 cases , 23 were benign tumors , 19, pleomporphic adenoma , 2 warthin's tumor,Results: 2 basal cell adenoma, while of 19 pleomorphic adenoma , male being 10 as compared to 9 female . The maximum of cases were seen in fourth and sixth decade followed by third and then fth decade. Malignant tumors has male to female ratio of 4:3 with predominance of third and sixth decade. All 23 cases of benign parotid tumors, i.e., 19 pleomorphic adenomas, 2 warthin's tumor and 2 basal cell adenomas were correctly diagnosed by FNAC. Hence the accuracy of FNAC in diagnosing benign parotid tumors in this series was 100%. In malignant tumors, ve of seven cases were correctly diagnosed by FNAC. The accuracy of FNAC in diagnosing malignant parotid tumors is 71.4 %. All pleomorphic adenomas were offered supercial parotidectomy except one where a total parotidectomy with conservation of facial nerve was done due to involvement of deep lobe. Of the other 4 benign tumors, all underwent supercial parotidectomy. In malignant tumors supercial parotidectomy with irradiation was offered in 3 cases, total conservative parotidectomy with irradiation in 1 case , total radical parotidectomy was offered in 3 cases. parotid gland tumors, has a male preponderance in both benign and malignant tumors, with 10:9 and 4:3 respectively. TheConclusion: accuracy of FNAC is 100% in benign tumors as compared to 71.4%. FNAC is a good tool in diagnosing benign parotid gland tumors, but should be cautiously interpreted in malignant tumors.
