Basal cell carcinoma after breast radiation: An uncommon disease with varying clinical presentations.

Current breast cancer care involves a multidisciplinary clinical approach for diagnosis and treatment including input from radiology, surgery, pathology, radiation, and medical oncology. Radiation is an integral part of the treatment for locoregionally confined breast cancer, and has well-recognized long-term risks of secondary malignancies, such as angiosarcomas. Basal cell carcinoma (BCC), a common skin malignancy, is not typically considered a radiation-induced carcinoma following breast cancer treatment. Our recent experience with 4 patients with vastly different presentations of BCC in previous radiation fields prompts the current report in order to alert clinicians to this entity.
