Leiomyosarcoma of the female breast
Tóm tắt
Leiomyosarcomas of the breast are rare tumors. Less than 15 such cases have been reported in the literature so far. In this paper authors describe a case of leiomyosarcoma of a female breast presenting as a firm lobulated mass, mimicking a phylloid tumor radiographically. By fine needle aspiration biopsy, on the smears discohesive malignant looking cells were conclusive to a poorly differentiated invasive ductal carcinoma of the breast. The mastectomy specimen contained a lobulated mass, microscopically showing a partly epithelioid spindle cell tumor, immunoreactive for vimentin, desmin, smooth muscle actin antibodies, and negative for epithelial markers, hormone and growth factor receptors. Axillary lymph nodes were free of tumor. A primary leiomyosarcoma of the breast was diagnosed.
