Abstract
PDF - Microglandular adenosis (MGA) of the breast is a rare, benign proliferative lesion but with a significant rate of associated carcinoma. Herein, we report an unusual case of metaplastic carcinoma with chondroid differentiation associated with typical MGA. Histologically, MGA showed a direct transition to metaplastic carcinoma without an intervening atypical MGA or ductal carcinoma in situ component. The immunohistochemical profile of the metaplastic carcinoma was mostly similar to that of MGA. In both areas, all the epithelial cells were positive for S-100 protein, but negative for estrogen receptor, progesterone receptor, HER2/neu, and epidermal growth factor receptor. An increase in the Ki-67 and p53 labelling index was observed from MGA to invasive carcinoma. To the best of our knowledge, this is the first case of metaplastic carcinoma with chondroid differentiation arising in MGA in Korea. This case supports the hypothesis that a subset of MGA may be a non-obligate morphologic precursor of breast carcinoma, especially the triple-negative subtype.

Abstract
PDF
- Smooth muscle cell metaplasia is an extremely rare form of stromal differentiation in fibroadenomas. We describe a case of fibroadenoma with exuberant smooth muscle cells in a 72-year-old woman. The mass was located in the upper central portion of the left breast. It was well circumscribed and its greatest dimension was 3 cm. Histologically, the glandular elements resembled the appearance of fibroadenoma, but the stromal elements were composed of spindle cell bundles with abundant eosinophilic cytoplasm and elongated cigar-shaped nuclei. Neither mitotic activity nor cellular atypia was seen. The stromal cells were immunohistochemically positive for smooth muscle actin, calponin, desmin, and estrogen receptor-beta, but negative for CD34, S-100 protein, p63, CD10, estrogen receptor-alpha, progesterone receptor and cytokeratin. These results proved that the stromal cells showed features of smooth muscle cells.
