[Congenital dermatofibrosarcoma protuberans: a case report].

Dermatofibrosarcoma protuberans is a rare low-grade fibrohistiocytic tumor with onset normally at ages between 20 and 50 years. It presents as a violaceous plaque or macule with an appearance suggestive of vascular lesion, on which nodular lesions appear later. Histological diagnosis is based on the presence of a spindle-cell tumor arranged in small bundles in a characteristic cartwheel pattern.

Atrophic dermatofibroma accompanied by aneurysmatic characteristics.

A 40-year-old man presented a painful haemorrhagic plaque on his chest in the same location where a nodular lesion had been presented for many years. After 2 months, the plaque was replaced by a depressed lesion. The lesion diagnosed as an anetoderma was excised and the biopsy showed an atrophic dermatofibroma accompanied by aneurysmatic characteristics.
