Abstract

Abstract: Intraosseous lipoma is a very rare benign lipoma, accounting for less than 0.1% of primary bone tumors. Incidentally found in most cases, it frequently involves the metaphysis of the long bones of the lower extremity or calcaneus but rarely occurs in the upper extremity. Intraosseous lipoma of the carpal bones, especially, has yet to be reported, except for 3 cases of scaphoid and capitate involvement. Herein, we report 2 cases of intraosseous lipoma in the capitate and hamate bones with a literature review. Two patients complained of wrist discomfort despite conservative treatment and were diagnosed by computed tomography, magnetic resonance imaging, and surgical biopsy. They were treated with intralesional curettage and autologous bone graft, and their symptoms improved and showed no evidence of recurrence, both clinically and radiologically.
