[Chronic radiodermatitis following coronaroplasty].

We report the case of a 72-year-old patient sent by his dermatologist in January 2009 for a back burn. His medical history reported one coronarography and two coronaroplasties between September and October 2005. This enabled us to form the diagnosis of chronic radiodermatitis after coronaroplasty from literature data. The occurrence of chronic radiodermatitis of the back and axilla area after cardiac catheterization has been observed in many countries. It almost always occurred in patients who underwent difficult and long-acting procedures leading to high doses radiation. There is not always acute radiodermatitis. Lesions appear between three and 30 months after exposure or even later. They are well-defined four-sided centimetrics lesions going from simple radiodystrophy to ulceration such as late radionecrosis requiring surgical coverage procedure.
