Abstract
Two patients with past experience of primary adenoid cystic carcinoma of the breast are reported. Patient 1 is a 59-year-old woman who was examined at another hospital due to complaint of a tumor in the left breast and mastalgia. After a confirmed diagnosis by biopsy, she was admitted to this hospital. Partial resection of the breast and axillary lymph node dissection were performed. It has been eight years now since the operation but the patient has been healthy with no relapse. Patient 2 is a 39-year-old woman who was examined due to complaint of a tumor in the left breast that was not comfirmed by diagnostic cytology. A biopsy was performed and adenoid cystic carcinoma was diagnosed. Partial resection of the left breast was performed but not axillary lymph node dissection. It has been two years now since the operation but the patient has been healthy with no relapse. In both patients, a confirmed diagnosis could not be obtained by diagnostic cytology and so biopsy was required. Adenoid cystic carcinoma originating from the breast is a comparatively rare disease. Reports of cases have increased recently, However, comprehensive reports are few and so the characteristies remain unclear. We have compiled 52 cases reported in Japan for a bibliographical review.
