BACKGROUND: Eccrine angiomatous hamartoma (EAH) is a rare benign cutaneous tumor characterized by the proliferation of eccrine glands and capillaries. OBJECTIVE: The aim of this study was to summarize the clinicopathological characteristics of EAH. METHODS: A retrospective chart review was performed on all patients diagnosed with EAH from 1977 to 2012 in the Union Hospital, Wuhan, P.R. China, and the clinicopathological features were compared with the cases reported in the literature. RESULTS: A total of 26 patients with EAH were identified. The male:female ratio was 1.2:1. EAH most commonly presents as a solitary (80.8%) plaque (50.0%) on the lower extremities (61.5%). Most patients presented with hyperhidrosis localizing to the lesion. Although most patients did not have major pain or anatomic deformity, one patient had severe pain as well as difficulty walking and moving, necessitating leg amputation. The histopathological findings showed typical features of EAH. CONCLUSION: EAH is a rare but characteristically benign skin hamartomatous condition. In rare occasions it can be associated with severe structural and functional impairment.
