title: Giant cell reaction of small bones.
abstract: A radiographically nonspecific lytic lesion in the middle phalanx of the index finger with microscopic evidence of a benign fibrous stroma with giant cells and osteoid was investigated in an 18-year-old man. Giant cell reaction is a rare, benign lesion of the small bones of the hands and feet. Trauma as the cause of a giant cell lesion poses an interesting question.
