Abstract
We report a rare case of noninvasive ductal carcinoma in a benign phyllodes tumor seen in a 26–year–old woman. The 4 cm right breast tumor, diagnosed in core needle biopsy as a benign phyllodes tumor. Contrast–enhanced computed tomography (CT) and magnetic resonance imaging (MRI) showed a benign pattern. Histologically, the resected specimen was diagnosed as a benign phyllodes tumor within noninvasive ductal carcinoma. The general postoperative course was satisfactory.
