Primary Intraosseous Cavernous Hemangioma of the Metacarpal Bone: A Very Rare Entity. Case Report

Abstract

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.

Intraosseous capillary haemangioma of a metacarpal bone

“…Solitary skeletal haemangioma of the extremities occurs predominantly in the lower extremity (73%) usually in the long bones, the tibia and femur being the most common sites (Zahid et al, 2000). The histology of reported intraosseous haemangiomas in the metacarpal region include three of the cavernous type (Martin and Rafferty, 1982; Simonetti et al, 2009; Zahid et al, 2000), one venous type (Simonetti et al, 2009) and one capillary type (Ghedira et al, 2011). Typical radiographic features of intraosseous haemangiomas include lace-like pattern and honeycombing.…”
