Abstract

BACKGROUND Eccrine porocarcinoma (EPC) is a rare malignant adnexal neoplasm with reported metastatic potential and undefined optimal treatment. OBJECTIVE This study reviews the clinical characteristics and outcomes of patients with EPC treated with Mohs micrographic surgery (MMS). MATERIALS AND METHODS The authors performed a retrospective chart review of patients with EPC treated by MMS at the Mayo Clinic from 1995 to 2013, recording patient demographics, tumor characteristics, MMS stages to clearance, follow-up, recurrence, metastasis, and mortality. RESULTS A total of 9 patients underwent MMS for EPC in 19 years. The average age was 64.2 years, with 6 males and 3 females. All patients were Caucasian. The head and lower extremity were the most common locations (44% each), with 1 on the forearm. Of the 9 tumors, 8 were located on the right side of the body. The mean preoperative tumor size and postoperative defect were 2.9 and 7.8 cm2, respectively, when 2 outliers were excluded. An average of 1.3 MMS stages was required for clearance. The mean postoperative follow-up was 3.3 years (range: 1-60 months). No tumors treated with MMS recurred, metastasized, or led to diseaserelated mortality. CONCLUSION Mohs micrographic surgery seems to be a useful treatment modality for EPC. This is one of the largest single-center series of EPC treated with MMS.
