A Case of Secondary Angiosarcoma of the Breast after Breast-conserving Surgery and Radiation: Review of Radiologic and Pathologic Findings

Angiosarcoma of the breast is a rare and potentially life-threatening disease. It can present as a palpable mass or subtle erythematous lesion, depending on the predisposing clinical factors. Erythematous skin lesions may be confused for a benign process, which may lead to a delay in diagnosis. We present a case of an 80-year-old woman who developed secondary angiosarcoma after undergoing breast-conserving therapy for Stage IA breast cancer. In this article, we review our experience with a case of secondary angiosarcoma of the breast and discuss the presentation, evaluation, and treatment of this disease. This case demonstrates the importance of vigilance regarding erythematous or papular breast lesions in the setting of prior local radiation.
