title: A Case Report of Adenoid Cystic Carcinoma of Breast- So Close Yet So Far from Triple Negative Breast Cancer.
abstract: Adenoid cystic carcinoma (ACC) of breast is a rare tumour with a low malignant potential. Though negative for oestrogen (ER), progesterone (PR) and human epidermal growth factor receptor 2 (Her2/neu), it is different from triple negative breast cancer (TNBC); ACC has an indolent course with a good prognosis.We present a case of a 40 year old premenopausal female initially diagnosed with ductal carcinoma in situ (DCIS) on core needle biopsy. She underwent breast-conserving surgery (BCS) and her final histopathological diagnosis was ACC. She subsequently underwent adjuvant external beam radiotherapy. The patient is on follow-up for more than a year with no recurrence till date.
