Eccrine porocarcinoma presenting as a recurrent wart

Eccrine porocarcinoma (EPC) is an exceedingly rare sweat gland tumor most commonly seen in older patients. Diagnosis of EPC is rare, representing a small percentage of cutaneous malignancies. In the absence of established guidelines, wide local excision (WLE) has traditionally been considered the standard treatment. However, there is growing evidence of increased local recurrence and nodal metastasis associated with WLE. More recently, Mohs micrographic surgery (MMS) is emerging as an effective treatment method with higher cure rates. We report a case of EPC presenting as a recurrent wart in a 36-year-old man that was successfully treated with MMS.
