Radiological findings of adenoid cystic carcinoma of the breast

Abstract

Adenoid cystic carcinoma (ACC) of the breast is a rare tumour that represents less than 0.1% of breast carcinomas. It has a triple-negative phenotype; however, it is associated with a benign course, and both lymph node involvement and distant metastasis are rare. We present seven cases of ACC of the breast diagnosed in our centre. We describe their radiological characteristics, and specifically highlight the findings from magnetic resonance imaging.
