Pattern of Fine Needle Aspiration Cytology of Superficially Palpable Lesions: One year hospital based study

Abstract

Introduction: This is a retrospective study on fine need aspiration cytology (FNCA) of superficially palpable lesions done in Shree Birendra Hospital, Chhauni, over a period of one year from 14th April 2008 to 13th April 2009.

Aim: The aim of this study was to review cytological diagnosis on superficially palpable lesions in various sites.

Methods: A total of 323 cytological diagnoses of palpable lumps performed in one year by pathologists were retrieved. Sites of FNA and diagnoses were analyzed and correlated with age and sex of the patients.

Results:This study has included 323 FNACs. Lymph node was the most common site for FNAC (32%), followed by breast (29%), thyroid (22%), and salivary gland (2%). Other site comprised 15% of cases. In lymph node, reactive lymphadenitis was the most common benign lesion (42.7%) and metastatic squamous cell carcinoma was the commonest malignant lesion(12.62%). In breast, benign proliferative breast disease was the most common(84.1%) and ductal carcinoma was commonest among malignant lesions(8.5%). Among thyroid lesions, benign proliferative thyroid disease was the commonest one (47.9%)followed by papillary carcinoma among malignant lesions(11.3%).Among salivary gland lesions, Chronic sialadenitis was common inflammatory lesion (37.5%) followed by pleomorphic adenoma among benign lesions(25%) and carcinoma comprised 25%. Lipoma was the commonest lesion ( 63%) from other sites.

Conclusion: Wide range of lesions, both benign and malignant, can be diagnosed by FNAC thus restricting surgery to cases only requiring further histopathological evaluation.
