title: Postirradiation Pseudosclerodermatous Panniculitis of the Leg: Report of a Case and Review of the Literature.
abstract: Postirradiation pseudosclerodermatous panniculitis presents as an erythematous indurated plaque, on a previously irradiated area. Histopathologically, thick and sclerotic septa and inflammatory infiltrate with foamy histiocytes and adiponecrosis are seen. To date, 12 cases have been reported worldwide. Hereby, we report the case of a 68-year-old woman who developed an indurated painful erythematous plaque on her right leg after radiotherapy for a soft tissue sarcoma, with a septal panniculitis and lobular adiponecrosis on histopathological examination. This is the 13th case reported and the second of extrathoracic location.
