Abstract

Commonly, epidermal inclusion cysts (EICs) are benign cutaneous lesions that are lined with stratified squamous epithelium and may occur in all body parts, including the breasts. EICs in the breast (EICB) are commonly encountered clinically; it may be under-reported because of their mild and nonspecific clinical presentation. Malignant transformation of EICs is extremely rare, occurring 0.011%-0.045%. Presently, we report a rare case of squamous cell carcinoma arising from an EICB of a woman with invasive ductal carcinoma.

표피낭종은 중층 편평상피로 구성되어 있는 진피층에서 흔하게 발생하는 양성질환으로, 유방을 포함한 신체 모든 부위에서 발생할 수 있다. 유방에서의 표피낭종은 임상에서 흔하게 볼 수 있으나, 임상적인 중요성이 떨어져 보고된 바가 적고, 표피낭종의 악성변형은 발생 빈도가 0.011%-0.045% 정도로 매우 드물다. 저자들은 침윤성 유관암의 과거력이 있는 환자에게서 발생한 유방의 표피낭종에서 기원한 편평세포암종에 대한 증례를 보고하고자 한다.
