Subcutaneous leiomyosarcoma developing in a radiation dermatitis.
A case of subcutaneous leiomyosarcoma developing in a skin affected by radiation dermatitis is presented. A 59-year-old patient had been suffering from radiation dermatitis induced by radiotherapy for a mediastinal tumor diagnosed at 24 years of age. Thirty-four years later, slow growing nodules developed in this lesion. Light and electron microscopic studies revealed that the tumor was a subcutaneous leiomyosarcoma. There is no previous report of a subcutaneous leiomyosarcoma developing in radiation dermatitis.
