Eccrine Poroma: A Case Report.

Eccrine poroma is a benign adnexal neoplasm often mistaken for pyogenic granuloma, skin tag, squamous cell carcinoma, and other soft-tissue tumors. We describe a 69-year-old woman with a soft-tissue mass on the lateral aspect of her right hallux that was initially clinically diagnosed as a pyogenic granuloma. Histologic examination proved that this mass was instead an eccrine poroma, the rare benign sweat gland tumor.
