Abstract

An intraosseous epidermal cyst is a benign cystic lesion that occurs in the bones. It is assumed to be caused by congenital causes or trauma, and because the cyst forms in the soft tissue surrounding the bone, it can lead to bone loss. Intraosseous epidermal cysts have a well-defined radiolucent lesion with cortical extension on radiography. Due to clinical and radiological signs being similar, it is vital to distinguish an intraosseous epidermal cyst from other diseases that develop at the distal phalanx. A rare example of intraosseous epidermal cysts at the distal phalanx is reported. We describe the clinical, radiological, and pathologic aspect of this lesion, as well as our current therapeutic strategy.
