Sarcomatoid Tumor following Radium Treatment

Haemangiomas are benign skin lesions that usually regress spontaneously, but radiotherapy has previously been used to assist the regression and healing of the lesions. Radium and X-rays were used as a treatment for benign skin lesions such as haemangioma until the carcinogenic effect of ionising radiation in humans was described. We report a patient diagnosed with a sarcomatoid carcinoma. Her past history was of particular interest since she had received radium treatment for a haemangioma at the same location more than 70 years before.
