Primary intraosseous orbital hemangioma of the lacrimal bone

Abstract

Intraosseus hemangioma comprises 1% of all benign tumors arising from the bone,1 of which only 5% are found in the orbit. Such orbital tumors are called primary intraosseus orbital hemangioma (PIOH).2 Fewer than 30 cases of PIOH have been described in the English literature, and only one case was reported to arise from the lacrimal bone.3–5 We report a case of PIOH arising from the lacrimal bone, with a review of the literature.
