BACKGROUND
Fine needle aspiration cytology (FNAC) is a method for the diagnosis of superficial
lesions like swellings of the salivary glands since many years. The present study
was undertaken to identify the patterns of salivary gland lesions (SGL) on FNAC
and histopathology specimens and also describe the age and sex distribution of
SGL.
METHODS
A total 319 cases of SGL were studied from June 2009 to July 2019 which included
both retrospective and prospective cases. A detailed history was taken, clinical and
necessary laboratory investigations were done; and then FNAC of salivary gland
was done. Histopathology examination of specimens was done whenever
available; FNAC and histopathology slides of retrospective cases were reviewed.
Correlation between cytomorphology and histomorphology was done only where
available.
RESULTS
The majority of cases was in the age group of 21 - 40 years (42.98 %) with female
predominance (53 %) and commonest gland involved was parotid gland (52.97
%) in both the sexes. 138 (43 %) cases were non-neoplastic lesions and 181 (57
%) were diagnosed as neoplastic lesions. Of the 138 non neoplastic lesions, on
cytology and histopathology, sialadenitis constituted 110 (79.71 %) cases; most
being chronic sialadenitis (107). Out of 181 neoplastic lesions, 142 (77.78 %) were
benign while 39 (22.22 %) cases were malignant. Pleomorphic adenoma was the
commonest benign neoplasm (71.27 %) and mucoepidermoid carcinoma (66.69
%) was the commonest malignant neoplasm. Histopathological correlation was
available in 37 cases.
CONCLUSIONS
FNAC is useful as an outdoor diagnostic procedure because of the availability of
earlier diagnosis in comparison with the histopathological diagnosis.
Histopathology correlation is helpful in cases where diagnosis at FNAC is difficult.
