Special Characteristics of Osteoid Osteoma in the Proximal Phalanx

Abstract

We report two cases of osteoid osteoma in the proximal phalanx. This is an uncommon location for the lesion and it has special clinical and radiological features. Both cases were successfully treated when an 'en bloc' excision of the lesion, including the nidus, was performed. Four operations were required in the first case.
