The association of carcinoma and sarcoma in a 48-year old woman bearing a large area of radiation dermatitis on the back, is described. At 22 years of age, the patient had pulmonary tuberculosis, was treated by pneumothorax and underwent many control radioscopic examinations for two years. One year later, she developed a radiodermatitis on her back, which had a fluctuating course up to the present time. The entire area of dermatitis was surgically removed: the histological examination showed a squamous-cell carcinoma and a spindle-cell sarcoma in two non contiguous areas.
