A case history is presented of a 41‐year‐old woman who developed an extraskeletal osteosarcoma of the upper chest wall at the site of therapeutic irradiation for breast carcinoma 8 years previously. The relation of the sarcoma to the irradiation was supported by the coexistence of a profound radiation angiitis. The development of this neoplasm, despite the relatively low total radiation dosage, is distinctly unusual.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
