Focal fibrocartilaginous dysplasia in the humerus.

Focal fibrocartilaginous dysplasia is an uncommon, benign bone lesion that causes deformity of the long bones in young children. It has most commonly been encountered in the proximal tibia, and very rarely in the long bones of the upper limb, that is, the proximal humerus, distal radius, ulna, and proximal phalanx. Only one case of focal fibrocartilaginous dysplasia of the proximal humerus has been reported previously.
