Abstract

Introduction: Adenoid cystic carcinoma is a neoplasm that is commonly of salivary gland origin. It could infrequently arise from other tissues such as breast in which case it behaves favorably despite belonging to triple-negative breast cancer subgroup.
Case presentation: We report a case of a 49-year-old female patient, who presented with right breast pain and upon work-up, was diagnosed with early-stage adenoid cystic carcinoma of the breast. She underwent breast conservation successfully and was advised to get evaluated for adjuvant radiotherapy. The work has been reported in line with the SCARE criteria (Agha et al., 2020).
Clinical discussion: Breast adenoid cystic carcinoma (BACC) is a rare distinct salivary gland-like carcinoma of the breast with similar morphological features to those seen in salivary gland adenoid cystic carcinoma. Surgical resection is the standard mode of treatment in BACC. The role of adjuvant chemotherapy has not proven beneficial in the management of BACC, owing to the similar survival rates seen in patients with and without chemotherapy.
Conclusion: Localized breast adenoid cystic carcinoma (BACC) is an indolent disease having optimal response to surgical resection alone and thus can omit adjuvant radiotherapy and chemotherapy when completely excised. Our case is unique as BACC is a rare clinical variant of breast cancer with a very low incidence rate.
