Adenoid Cystic Carcinoma of Breast: A Rare Entity

Adenoid cystic carcinoma (ACC) is a rare form of breast cancer (BC) with favourable prognosis. Clinically adenoid cystic carcinoma of breast (BACC) can be confused with phyllodes tumour as both may have an indolent course and present as a discreet mass without evidence of distant spread which might lead to dilemma in diagnosis of this rare form of BC. It is characterized by being ER-negative/PR-negative and rare axillary lymph node involvement. Due to its rarity, a treatment guideline of this form of breast cancer has not been established. Herein we report a case of ACC to create an awareness of this less known entity.
