Radiologic Findings of Microglandular Adenosis of the Breast mimicking Breast Carcinoma: Report of a Case

초록

Microglandular adenosis (MA) of the breast is an extremely rare, benign lesion. Histologically, small round glands lacking a myoepithelial layer infiltrates normal stroma which makes it difficult to distinguish from welldifferentiated breast cancer. Breast carcinoma arising in MA has been reported up to 27%, so although it is known as a benign lesion without local spread or metastasis, complete excision is recommended based on a core needle biopsy (1-4). Herein, we report a case of MA which mimics invasive carcinoma on radiologic imaging. To our knowledge, this is the first case of MA confused with carcinoma reported in the radiologic literature.
