Abstract
The patient was a woman in her seventies who was detected to have a right breast mass on CT scan performed at another hospital. Mammography (MMG) revealed a tumor shadow of a category 3 in the right C, and ultrasonography (US) showed a 9.8 × 10.7 mm tumor of a category 3 in the right C area. On magnetic resonance imaging (MRI), it was a clearly demarcated oval-shaped tumor, which showed low signal intensity on T1-weighted images and heterogeneously high signal intensity on T2-weighted images. Dynamic CT scan revealed dotted enhancement in the inner part in an early phase which spread over the whole with time. Aspiration biopsy cytology (ABC) resulted in Class III. Following a core needle biopsy (CNB), invasive ductal carcinoma was diagnosed. Preoperative examinations revealed no distant metastases. At surgery, we performed right partial mastectomy and sentinel lymph nodes biopsy. The histopathological diagnosis was atypical epithelioid fibrous histiocytoma.
As we have experienced a case of benign fibrous histiocytoma arisen in the breast which is rare, we here present the case.
