Department of Medicine, University of Wisconsin-Madison 53705.


Eccrine porocarcinoma is a rare tumor of the skin. We report a case on the chin that was successfully treated with Mohs surgery. In our review of the world's literature 105 cases were compiled. The tumor most often occurs in the elderly and affects men more frequently than women. It may develop from a preexisting benign poroma and may also appear as a verrucous or nodular, ulcerative growth. Approximately 50% of the tumors occur on the lower extremities; the leg is the most common site. Microscopically the tumor demonstrates both intraepidermal and dermal invasion and is capable of forming satellite lesions and in-transit metastases when lymphatic vessels are invaded. The local recurrence and regional metastatic rates are both approximately 20%. Distant metastasis occurs in 12% of cases. The mortality rate is more than 65% when regional nodes are involved.
