The firat caae of hemangioma originating in the skeletal muscle was reported by Linton in 1843. Hemangiama involving the skeletal muscle ia less common and the correct preoperative diagnosis is often not made even tbough they attain considerable size. These tumors have remained asymptamatic and undetected by their hosta. We experienced 5 cases of hemangiama in the skeletal muscle for 2 years since 1979 and the diagnosis were confirmed clinicopathologically.
