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

Invasive Breast Carcinoma Arising in Microglandular Adenosis: Two Case Reports
Microglandular adenosis (MGA) is a rare benign disease that shows an infiltrative growth pattern of small glands, and it may progress to include atypia and carcinoma. Here we report two cases of breast carcinoma arising in MGA. Case 1 was a 44-year-old woman with a previous history of ductal carcinoma in situ in her right breast. During a follow-up, a 1.8 cm mass-like lesion was found in her le...
متن کاملMammary Carcinoma Arising in Microglandular Adenosis: A Report of Five Cases
Mammary carcinoma arising in microglandular adenosis (MGA) is extremely rare, and MGA is regarded as a non-obligate precursor of triple-negative breast cancer. We report five cases of carcinoma arising in MGA of the breast. All cases showed a spectrum of proliferative lesions ranging from MGA to atypical MGA, ductal carcinoma in situ or invasive carcinoma. Immunohistochemically, all cases were ...
متن کاملMicroglandular Adenosis
Microglandular adenosis (MGA) of the breast is a very rare and benign proliferative lesion. Most patients complain of a palpable breast mass that may arouse a clinical suspicion of breast cancer. Histopathologically, it is hard to distinguish MGA from breast cancer because of the lack of a myoepithelial layer and infiltrative proliferation. Several studies have reported a strong relationship be...
متن کاملAdenomyoepithelioma with Ductal Carcinoma In Situ: A Case Report and Review of the Literature
Adenomyoepithelioma (AME) with microglandular adenosis-like growth pattern and superimposed ductal carcinoma in situ (DCIS) was identified in a 55-year-old female after biopsy of an atypical lesion identified through routine breast screening. A literature review reveals that this association has rarely been described.
متن کاملAcinic Cell Carcinoma of the Breast Arising in Microglandular Adenosis
Acinic cell carcinoma is a rare breast tumour belonging to salivary gland-like tumours of the breast. They are "triple-negative" breast cancers even if their biological behaviour seems to be more favourable. Herein we present an acinic cell carcinoma arising on a background of typical and atypical microglandular adenosis in a 58-year-old woman, along with a review of the literature.
