Fine Needle Aspiration Cytology of Eccrine Spiradenoma of Back: Report of a Rare Case

Abstract

Eccrine spiradenoma is an uncommon benign adnexal tumor. Cytological features of eccrine spiradenoma have been described very rarely in English literature. In the present case, we are describing a case of eccrine spiradenoma of back, which was diagnosed by fine-needle aspiration cytology and subsequently confirmed by histopathology. Its cytology revealed tight multilayered clusters of uniform benign cuboidal epithelial cells along with spindle-shaped myoepithelial cells and occasional lymphocytes.
