Eccrine porocarcinoma treated with Mohs micrographic surgery: A report of five cases

BACKGROUND. Eccrine porocarcinoma is a rare, locally aggressive, potentiall y fatal neoplasm. While wide local excision has traditionally been the trea tment of choice, recurrences following excision are common. OBJECTIVE. The purpose of this study was to review the traditional treatmen ts of eccrine porocarcinoma as well as to introduce Mohs micrographic surge ry as an alternative to wide local excision. METHODS. We reviewed all cases of eccrine porocarcinoma seen at Emory Unive rsity 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 mi crographic 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 microgra phic surgery may be an effective treatment for eccrine porocarcinoma.
