Adenoid cystic carcinoma, report of a case

Introduction: Adenoid cystic carcinoma (CAQ) is a typical tumor of the salivary glands and infrequent in the breast (less than 0.1%). It stands out for being triple negative with a favorable prognosis. Its infrequency and slow progression mean that today there is no consensus regarding its therapeutic management and follow-up. Objective: To provide a new case to learn more about the nature, management and evolution of this type of neoplasm. Material and methods: We analyzed the data collected in our case and compared it with what was published in the literature. Results: a typical triple negative case is presented, with a large size with respect to the breast (T2), so it was decided to perform a simple mastectomy as initial treatment with immediate reconstruction due to the absence of axillary involvement. Subsequently, it was decided not to apply adjuvant treatment since the tumor was not aggressive, the hormone receptors were negative, and the final lesion was less than 5cm with wide margins and no evidence of lymphovascular invasion. Conclusion: To date, breast CAQ continues to present uncertain management and follow-up given that we do not have enough data in the literature to know its evolution correctly, therefore more studies are needed with the intention of being able to standardize treatment and surveillance of this tumor.
