[An unusual case of herpes circinata (author's transl)]

A 61-year-old patient presented with an eczematous patch on the left wrist, suspect of a contact dermatitis to his watch. This lesion did not respond to the usual topical treatment. On the contrary, new lesions appeared on both forearms. A fungous culture was positive and confirmed the diagnosis of tinea circinata. Appropriate treatment allowed a complete cure within 1 month.
