Abstract

Ectopic breast tissue can persist in the axilla due to lack of involution of mammary glands along the mammary lines. It is rare in men, and the malignant transformation to breast cancer has occasionally been described. Differential diagnosis of any axillary tumor should include breast cancer arising at ectopic sites.
