uncommon presentation of giant cell tumor

ABSTRACT

Giant Cell Tumors commonly occur at the ends of long bones. However in rare cases, they can occur in the bones of the hands and feet. Tumors in these locations occur in younger patients; in addition, these tumors are more commonly multifocal and are associated with a higher risk for local recurrence than tumors at the ends of long bones. Since lesions in the small bones may be multifocal, a patient with a giant cell tumor of the small bones should undergo a skeletal survey to exclude similar lesions elsewhere. Primary surgical treatment ranges from curettage or excision with or without bone grafting to amputation. The success of surgical treatment depends on the completeness with which the tumor was removed. We are presenting a case report of a 34 year old female, who presented with a swelling in the right hand, following trauma. X-ray of the hand showed an osteolytic expansile lesion at the base of the 1[st] metacarpal bone. The lesion was initially curetted and then treated by local resection with bone grafting. Histological examination revealed a typical benign giant cell tumor composed of closely packed stromal cells with a variable admixture of giant cells. Follow up at the end of one year did not reveal any recurrence of the tumor
