Intraosseous keratin cyst of the distal phalanx

Rohini Prasad et al. Indian J Plast Surg. 2015 May-Aug.

Abstract

Keratin or epidermoid cysts of the phalanges are rare lesions mimicking osteolytic lesions such as infection, malignancy and other tumours. Definitive diagnosis can be made by histopathology only and treatment is by simple excision and curettage. We present a case of intraosseous keratin cyst of the distal phalanx and review of literature.

Keywords: Intraosseous; keratin or epidermoid cyst; lytic bone lesion.
