Rare benign tumors of the breast

초록

Rare benign tumors of the brest Case 1; We present herein the case of a 53-year-old woman found to have a pleomorphic adenoma, or so-called mixed tumor, of the breast. Macroscopically the excised mass was well circumscrobed and the cut surface was homogenouly yellowish-white. Microscopically, the tumor was clearly demarcated with a focal fibrous capsule, and composed of epithelial and mesenchymal components with chondromyxoid areas.Mitosis and anaplasia were not identified within the tumor. Case 2; Schwannoma arising within breast parenchyma is rare. we report a case of a 23-year old woman presented with a palpable mass of right breast for 2 years.as pleomorphic adenoma and schwannoma are rare benign tumors in the breast, these cases have been mistaken for a malignant tumor or fibroadenoma, clinically. Thus an awareness of these diseases in the breast will help to prevent misdiagnosis and overaggressive surgery.
