Abstract

Summary: Breast cancer arising within fibroadenomas (BcaFad) is a very rare finding. BcaFad occurs mostly in women between the ages of 40 and 50. This report details the unique case of an 18-year-old woman with bcafad. We present an 18-year-old woman with a ductal carcinoma in situ (DCIS) arising within a fibroadenoma. This is the youngest reported case of BcaFad in the literature. Clinically, the mass presented characteristics of a benign breast lump. Microscopically, an atypical proliferation of luminal epithelial cells was classified as a low-grade DCIS. As a very rare presentation at an especially unusual age, this case challenges the current risk evaluation and management in young women diagnosed with fibroadenoma.
