Abstract: Objective: To investigate the clinicopathological characteristics of adenoid cystic carcinoma(ACC) in breast for improving the recognition and diagnosis of ACC. Method: Ten female patients with ACC were enrolled. Clinical symptoms and pathological characteristics were reviewed, immunohistochemical phenotyping of biopsies of ACC lesions were detected, and the related data were analyzed in combination with relevant references. Results: Patients were female, with mean age of (61±14) years. Six cases had lesions in left-breast and four cases in right, mostly in the upper outer quadrant. The main clinical manifestation was expansive growth, and the ACC tumor size ranged from 1 to 4 cm, and histologically resembled glandular, tubular and solid tumor. The tumor cells were immunohistochemically negative for ER, PR, HER-2 expression and positive for CD117 expression. Proliferation marker Ki67 ranged from 5%-30%. The median follow-up of these 9 cases ranged from 4-110 months. One patient died of multiple organ failure, and the other eight patients were alive and well with no evidence of disease. Conclusions: ACC of breast is a rare subtype of breast cancer and exhibits an indolent clinical behavior. ACC has its own special histologic characteristics, and differentiation with other breast benign and malignant tumor is needed.
