Cytohistological Study of Salivary Gland Lesions

Abstract

Salivary Gland lesions include non-neoplastic and neoplastic lesions. The majority of neoplasms are benign. The present study is a prospective study of 65 cases of salivary gland lesions, conducted at Gandhi Hospital/Gandhi Medical College, Hyderabad, Telangana State, India over a period of five years. Parotid gland was the most frequently involved among all salivary glands. The age range of the patients was from 8 to 65 years. Non-neoplastic lesions occurred in all ages, whereas benign tumors were common in adults and malignancies were common in older age groups. There was a slight female preponderance in the ratio of 1.3:1. FNAC was performed with 23/24 gauge needle without local anaesthesia. Air dried and 95% ethyl alcohol fixed wet smears were stained with Giemsa, Papanicoulou and Hematoxylin & Eosin stains. Surgical specimens of these cases fixed in 10% formalin were received at the Department of Pathology. After processing the tissues, sections were cut from the paraffin wax blocks and stained with Hematoxylin and Eosin. Cytohistological correlation was done. The high accuracy, sensitivity and specificity of FNAC is very much helpful as a preoperative procedure in the diagnosis of salivary gland lesions. FNAC is useful for rapid, reliable and early diagnosis of all salivary gland lesions.
