Adenoid cystic carcinoma of breast: a case report

摘要

Abstract Introduction: Adenoid cystic carcinoma (ACC) of the breast is a rare neoplasm, accounting for less than 1% of breast carcinomas. The aim of our study is to describe the epidemiological and clinicopathological characteristics, the treatment and the prognosis of this type of breast tumor. Case report: We report a new observation occurring in a 53-year-old female patient, who consulted for a left breast nodule. The ultrasound and mammography showed that it was a well-limited mass. Diagnosis was based on a histopathological exam completed by histochimical techniques. Estrogen and progesterone receptors were positive. The patient was treated by lumpectomy with adjuvant radiotherapy and hormonal therapy.Discussion: ACC of the breast has a favorable prognosis. The diagnosis is made by histological examination with histochemical or immunohistochemical techniques. The treatment is not well established. It consists of lumpectomy with radiation or mastectomy. Lymph node involvement or distant metastases seldom occur.
