Adenoid cystic carcinomas of the breast (bACCs) are rare triple-negative basal-like breast carcinomas. They account for less than 0.1% of all breast cancers [1]. This variant of adenocarcinoma is usually seen in salivary glands but has also been reported in other organs, i.e. breast, skin, lung, cervix, larynx and bartholin gland [2]. Unlike that of salivary gland, bACCs have a good prognosis with rare axillary metastases. They can metastasize to the lungs and local recurrences are less likely in cases with mastectomy [3]. We report a case of bACC diagnosed on histopathology and confirmed by immunohistochemistry.
