Intraosseous epidermoid cyst discovered in the distal phalanx of a thumb: a case report.

Intraosseous epidermoid cyst is considered a rare benign inclusion cyst found mainly in the skull and phalanges. Once the cyst is differentiated from other similar lesions, the cyst can be treated with simple curettage, seldom requiring additional managements. We experienced this rare case that had been treated successfully without complication.
