Penile neurilemmoma: Utility of fine-needle aspiration cytology in diagnosis of a rare entity

Abstract

Subcutaneous lesions in the penis are of rare occurrence and encompass benign as well as malignant tumors. These include lipomas, leiomyomas, neurilemmomas and their malignant counterparts. A surgical excision at this site carries the risk of postoperative penile curvature and erectile dysfunction. We report a rare case of penile neurilemmoma which presented as a subcutaneous nodule on the dorsal surface of the penis. A fine-needle aspiration was performed which aided in the preoperative diagnosis and guided the extent of excision. We report this case to highlight the importance of needle aspiration as a simple outdoor procedure for penile lesions which can aid surgical approach and postoperative outcome.
