[Cystic adenoid carcinoma of the mammary gland].
Adenoid cystic carcinoma of the mammary gland is considered a rare entity with a favourable prognosis, accounts for < 1% of the breast malignancies. We report herein the case of a 57 year old woman who presented a breast mass. A mastectomy with axillary lymph node dissection was performed. None of 15 axillary lymph nodes contained metastases, and the patient remains well and free from recurrence 12 months after her operation.
