Intraosseous Epidermoid Cyst of Distal Phalanx of Fingers

Abstract

Intraosseous epidermoid cysts of fingers are uncommon lesions. We reported two cases with intraosseous epidermoid cysts of distal phalanx of fingers. Case 1 was a 61-year-old woman with a swelling of the left middle finger without history of trauma. Case 2 was a 47-year-old male with a crushing injury of his right thumb. On radiographic findings, a well-circumscribed osteolytic lesion in distal phalanges was noted. Unexpectedly, histological examinations showed intraosseous epidermoid cyst.
