Multicentric giant-cell tumor of bone
FH Sim, DC Dahlin and JW Beabout
The presence of more than one distinct giant-cell tumor in the same patient
is rare; seven cases have been reported in the literature. The present
series involves eleven patients with thirty-five individual tumors.
Multifocal giant-cell tumors may pose a diagnostic problem. It is difficult
to distinguish a multicentric giant-cell tumor from a primary giant-cell
tumor with metastatic spread. This problem is magnified when the second
lesion is not noted at the onset or is metaphyseal in location. Moreover,
these lesions present a therapeutic challenge to the surgeon. Multiple
lesions tend to exhibit the same aggressive clinical behavior as a solitary
giant-cell tumor. A high recurrence rate after curettage indicates that
aggressive surgical management is necessary.
