We have reported a case of giant cell tumor in the metacarpal bone previously, finding the giant cell tumor of short tubular bone is very rare.
We have recently experienced another case of giant cell tumor which occured in the first metacarpal bone of a young man. He was 17 years old, and was complaining of pain and swelling in the left metacarpal portion.
Roentgenogram revealed the significant destructive lesion in the metacarpal bone. 8 months after primary curettage and bone grafting, recurrence had occured.
Curretage of the bony lesion and bone grafting was carried out for the recurrent bone tumor.
Histologically, no evidence of malignancy was found.
