BACKGROUND. Eccrine porocarcinoma is a rare, locally aggressive, potentially fatal neoplasm. While wide local excision has traditionally been the treatment of choice, recurrences following excision are common. OBJECTIVE. The purpose of this study was to review the traditional treatments of eccrine porocarcinoma as well as to introduce Mohs micrographic surgery as an alternative to wide local excision. METHODS. We reviewed all cases of eccrine porocarcinoma seen at Emory University between 1985 and 1999. All cases were treated definitively with Mohs micrographic surgery. The clinical characteristics and outcome of each case are summarized. RESULTS. Five patients with eccrine porocarcinoma were treated with Mohs micrographic surgery. There have been no recurrences to date, with an average follow-up of 2.1 years (ranging from 5 months to 4 years). CONCLUSION. Follow-up of five patients supports the view that Mohs micrographic surgery may be an effective treatment for eccrine porocarcinoma.
