Osteolipoma of the hand: a case report

A 61-year-old, healthy woman presented with a six-month history of a mass on the radial volar aspect of her dominant right hand. The patient had a history of trauma to the hand six years previously. Radiographs showed a bony lesion in the index metacarpal shaft and the MRI showed a bony lesion and soft tissue mass suggestive of a parosteal lipoma. Surgical excision of the lesion revealed a lipoma overlying a bony exostosis or osteolipoma of the hand. Post-operatively, the patient's symptoms resolved and she had no recurrence of the tumor.
