ABSTRACT
Background: Lymphadenopathy is an age old affliction of mankind and a very common presentation in clinical practice. The main purpose of an FNA biopsy of abnormal peripheral lymph nodes is to determine whether further surgical excision of the lymph node is indicated for histopathological examination. The aim of the present study was to evaluate the role of fine needle aspiration cytology in patients with superficial lymphadenopathy and to correlate with histopathology wherever possible.Methods: A two-year study was undertaken at the Central Diagnostic Laboratory at A.J. Institute of Medical Sciences, Mangalore. Patients of all age groups referred to the Central Diagnostic Laboratory for FNA of superficial lymph nodes were included in the study. All the slides of the cases were reviewed and impression recorded.Results: Out of 200 cases, 73% were non neoplastic, 27% were neoplastic. Cases occurred most commonly in age group of 21-30 years. The male to female ratio was 1.7:1 and most common site of lymph node aspiration was cervical lymph node in (n =107) 53.5% cases. Reactive hyperplasia was the most common non- neoplastic cause of lymphadenopathy seen in 34.5% cases and metastasis to lymph node was the most common cause of neoplastic lymphadenopathy seen in 22% of the cases. The sensitivity was 90%, specificity was 100% and accuracy was 96.2%.Conclusions: FNA is a very efficient, simple, safe, inexpensive and economical test for detecting the various causes of lymphadenopathy.
