[Radiation-induced Favre-Racouchot disease].

A 71-year-old man presented with disfiguring skin changes of the nose and cheek. The patient had undergone a surgery of a malignant melanoma of the right paranasal sinus and then 5 months later received radiation therapy with 60 Gy total dose to the endonasal area. Physical examination revealed elastosis, open and closed comedones, and cysts in the field of radiation exposure. Taking in account the exclusive affection of the irradiated skin, we diagnosed a radiation-induced Favre-Racouchot disease. We recommended topical treatment with vitamin A derivatives in combination with physical comedo extraction.
