Primary intraosseous cavernous hemangioma of the metacarpal bone: a very rare entity. Case report.

Intraosseous cavernomas are very rare benign lesions representing less than 1% of all skeletal tumors and most frequently observed in vertebrae and head and neck bones. Solitary hemangiomas of the hand bones are exceptionally rare. We report a case of this neoplasm in the distal epiphysis of the third metacarpal bone in a 68-year-old man, along with the clinicopathological findings. The differential diagnosis and a review of the literature are discussed.
