파열되어 반복적으로 농양을 형성한 유방의 표피낭종

Abstract

Epidermal inclusion cysts are benign cutaneous or subcutaneous lesions, which are filled with lamellated keratin and lined with stratified squamous epithelium. They are commonly found in the face, neck, trunk, and rare in the breast. Although most epidermal inclusion cysts are harmless, ruptured cysts can lead to infection or abscess and which often require surgical removal. Only few cases of ruptured epidermal cyst in breast have been reported, and furthermore, occurrence of ruptured epidermal cyst in the breast parenchyma is very rare. We now report a rare case of a ruptured epidermal inclusion cyst arising in the breast parenchyma.
