Treatment of advanced malignant eccrine poroma with locoregional chemotherapy

Malignant eccrine poroma is a rare disease with approximately 200 cases reported in the literature. Regional cutaneous and systemic metastases are rarely observed and their management has been generally unsuccessful. We report on a case in which topical 5‐fluorouracil application and intra‐arterial chemotherapy with docetaxel resulted in a histologically confirmed complete response of multiple regional skin metastases for more than 2 years. Despite intravenous administration of docetaxel, slow progression of systemic disease was observed.
