[Juxtacortical osteogenic sarcoma localized in the hand. Presentation of 2 cases].

Until the present time, only four cases of parosteal osteogenic sarcoma arising from the bones of the hand have been reported in the literature. The purpose of this paper is to document two new cases of parosteal osteogenic sarcoma of the hand. These tumours were localized in the proximal phalanx of the ring finger in one case and in the third metacarpal bone, in the other case. Both patients were treated by amputation of the involved metacarpo-digital ray and radiation therapy. They were free of the disease six years and eighteen months, respectively, after treatment.
