Abstract

Giant cell tumor is a benign tumor of bone with a predilection for juxta-articular locations. Although not malignant, giant cell tumor often exhibits unpredictable and locally aggressive behavior, and in rare cases can metastasize in the absence of histologic malignancy. Partial tumor necrosis has been infrequently reported within typical giant cell tumor. A 17-year-old girl presented with a right distal femur giant cell tumor associated with complete tumor necrosis on histopathologic analysis. The etiology, prevalence, and implications of complete necrosis in previously untreated giant cell tumor of bone remain unclear, as there are no previously published reports. Despite the complete necrosis evident in our patient, she nonetheless presented with pain. There were no radiographic signs of the necrotic tumor space remodeling with new bone. The patient was treated with standard extended intralesional curetting through a generous cortical window permitting visualization of the entire lesion, and systematic high speed burring and thermal electrocautery ablation of the periphery, followed by micro particulate allogenic bone grafting. At short-term follow-up, she had healed well with no evidence of tumor recurrence. This article presents the first case, to our knowledge, of complete spontaneous tumor necrosis in a previously untreated bone giant cell tumor. Increased understanding of spontaneous tumor necrosis associated with giant cell tumor may help guided future targeted medical and surgical treatment modalities.
