Abstract

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

골내 표피낭종은 드문 양성 낭성 병변이다. 이는 선천적인 요인이나 외상의 결과로 사료되며, 골 주변의 연부 조직에서 발생하기 때문에 골 파괴를 유발할 수 있다. 골내 표피낭종의 단순방사선 소견은 피질골의 팽대를 동반한, 경계가 명확한 방사선 투과성 병변이다. 임상적, 방사선학적 소견이 유사하기 때문에 원위 지골에서 발생한 다른 질환들과 골내 표피낭종을 감별하는 것이 중요하다. 저자들은 원위 지골에서 발생한 골내 표피낭종의 2개의 드문 증례를 보고하고자 한다.
