study of fine needle aspiration cytology [FNAC] appearance of salivary gland tumors

ABSTRACT

To analyse the Fine Needle Aspiration Cytology [FNAC] appearance of salivary glands tumors diagnosed at AFIP Rawalpindi. The study was carried out in the Histopathology department of AFIP. A total of 95 patients were selected from January 2009 to December 2010. All the patients diagnosed as salivary gland tumors were included in the study. The FNA was performed on these patients and the material was spread on slides. These slides were then stained with Hematoxylin/Eosin and Haema color [Modified Giemsa Stain]. Routine light microscopy was performed on these cases and diagnosis was made. The data analysis was performed using SPSS version 14. The study included 95 patients with salivary gland swellings. There were 50 [60%] male and 45 [40%] female patients with an age range of 13-75 years. Pleomorphic adenoma was the most common diagnosis, 48 cases [47.8%], followed by Mucoepidermoid Carcinoma 10 cases, and Adenoid Cystic Carcinoma 7 cases. Others tumors included 4 cases of Adenocarcinoma [4.2%], 3 cases of Warthin's tumor [4%], one case each of Squamous cell Carcinoma [0.6%], Oxyphilic cell tumor [0.6%] and Benign Hemangiomatous Lesion [0.6%]. Thirteen cases of malignant neoplasms [15.4%] and 7 cases of benign neoplasms [7.1%] could not be exactly typed. It is concluded that Pleomorphic Adenoma was the most common salivary gland tumor diagnosed on FNAC, followed by Mucoepidermoid Carcinoma and Adenoid Cystic Carcinoma
