Abstract

Osteoblastoma is classically described as a more aggressive form benign bone forming tumors that mainly occurs in the axial skeleton and spine. There have been few case reports and case series of this lesion occurring in the carpal ones, and only three reported cases occurring in the capitate, which were all treated successfully with curettage and bone grafting. Here we present the first reported case of a patient who was diagnosed with osteoblastoma of the capitate who had disease recurrence despite two attempts at curettage and bone grafting followed by capitate resection, ultimately leading to malignant transformation.
