Abstract Adenoid cystic carcinoma (ACC) of the breast is an exceptionally rare malignancy, accounting for less than 0.1% of all breast cancer cases. It typically affects women between the ages of 50 and 60 and most commonly presents as a subareolar mass or breast pain. Radiological findings are often non-specific; however, diagnosis can be established through fine-needle aspiration cytology. In this report, we present the case of a 69-year-old woman who presented with pain in the outer quadrants of the right breast. Lumpectomy revealed adenoid cystic carcinoma, and the patient subsequently received postoperative radiotherapy. At 20 months of follow-up, no signs of recurrence or metastasis were observed. In conclusion, mammary ACC is a rare form of breast cancer. While surgical excision remains the cornerstone of treatment, the optimal approach to adjuvant therapy remains unclear due to the tumor’s rarity.
