Description
Medullary carcinoma is a rare histological breast tumor type, accounting for 1-2% of all breast cancers. The tumor is generally well demarcated and its margin is relatively clear. Histologically, large non-polarized and immature cancer cells with clear nucleoli are common and proliferative, resembling the medulla. The tumors are usually negative for ER, PgR, and HER2 (triple negative). The intraductal component is equivocal and the interstitial lymphocyte permeation is extremely prominent. We experienced a case of medullary carcinoma located in the axillary region, so that it was difficult to differentiate from axillary lymph node metastasis.<BR>A 63-year-old postmenopausal woman was admitted to our hospital with a right axillary mass. Imaging examinations revealed a tumor 3 cm in diameter in the right axillary adipose tissue and interpectoral lymph node swelling 1.4 cm in diameter. Fine needle aspiration cytology and core needle biopsy suggested metastatic carcinoma from an unknown primary tumor. She underwent en-bloc resection including the tumor, axillary to the Rotter's lymph nodes, and the skin and mammary tissue of the outer/upper quadrant. The final histopathological diagnosis was primary medullary breast carcinoma (pT2N1aM0 ; Stage IIB) arising from the marginal mammary gland of the outer/upper quadrant.
