Ectopic cutaneous Schistosoma haematobium in the inguinal region.

A 66-year-old man with indolent systemic mastocytosis presented with a plaque-like cutaneous lesion at his right inguinal region. He had travelled to various African countries in the years before. Pathological examination revealed a granulomatous infiltrate surrounding eggs of Schistosoma haematobium. Ectopic cutaneous schistosomiasis was therefore diagnosed, for which he was treated with Praziquantel.
