Clinical and Radiological Profile of Ten Interesting Though Rare Presentations of Giant Cell Tumor of Bone.

Giant cell tumor (GCT) is a benign but locally aggressive lesion of the bone. They are common in skeletally matured individuals with female preponderance. Unusual presentations can occur rarely. This study aims to find out the clinical and radiological profile of ten rare presentations of GCT. We have conducted a retrospective analysis of medical records of ten interesting presentations of giant cell tumor of bone. There was a patient with soft-tissue recurrence after excision. In five cases, the GCT occurred at rare sites and a case to discuss the radiological dilemma in the diagnosis. One case of pathological fracture, another case of seeding of tumor cells in the graft donor site, and a case of pulmonary metastasis were included. There were seven females, two males, and a boy. Out of ten patients, all except two cases were primarily treated at our institution. Clinical profiles of soft-tissue recurrence, rare sites of occurrence, diagnostic dilemma, pathological fracture, seeding at donor site, and metastasis were analyzed and presented. GCT, even though it is a benign lesion, can have a variety of clinical presentations and complications.
