Fine Needle Aspiration of Glomangioma Knee - A Case Report

Abstract

Glomus tumor, a benign neoplastic proliferation of modified smooth muscle cells characteristically occurs in a digital subungual location and presents with localised pain. Extra-digital locations that have been described so far include bone, tongue, stomach, rectum, lung, mediastinum, sacrum, coccyx and head and neck areas. Though the histology of glomus tumor is very characteristic, cytological features are poorly defined. Less than ten cases describing cytologic features have been reported so far. We present a case of glomus tumor of the knee joint detected on fine needle aspiration and confirmed later on histopathology, in a 55-year-old male. JMS 2011;14(2):71-73
