Epidermal inclusion cyst is a common cutaneous condition. However, epidermal cyst deep in the breast parenchyma is rare. Diagnosis can be difficult if there is no suspicious clinical history. An onion-ring appearance on ultrasonography with alternating concentric hyperechoic and hypoechoic rings has been described, corresponding to the laminated keratin. Biopsy should be performed if clinically indicated. We report a case of breast epidermal cyst in a Chinese woman.
