Synchronous carcinoma and soft-tissue sarcoma. The importance of searching for incidental radiation exposure.

Abstract

A 68-year-old woman was found to have synchronous soft-tissue sarcoma of the anterior chest wall and adenocarcinoma of the breast. During her initial interview, she denied prior radiation therapy. On further questioning, it was learned that the patient had been treated for tuberculosis, as a young woman, by the induction of a pneumothorax that was monitored by repeated chest fluoroscopies. Biologically important doses of ionizing radiation can be given as an incidental part of a variety of medical treatments. The importance of searching for atypical radiation exposures, particularly in patients with unusual tumor presentations, is stressed.
