Epidermal Cyst in the Breast: A Diagnostic Dilemma

Epidermal cyst [10] and panniculitis are relatively uncommon conditions [2]. A combination of these arising in the breast is extremely rare. We report a case of epidermal cyst with panniculitis in the breast. A patient presented with a large breast lump of 5 cm in the right breast. Sonography showed a well-defined, central hyperechoic mass. A giant fibroadenoma was suspected clinically and based on imaging. Fine needle aspiration revealed a benign breast lump. The lump was excised, and the specimen revealed an epidermal cyst with panniculitis.
