교근내에 발생한 혈관종의 치험례

Intramuscular hemangioma of the masseter muscle - case report -

Hemangiomas are relatively common tumors which are characterized by a proliferation of blood vessels. These lesions are usually present from birth and are considered by most to be hamartomas rather than true neoplasms. A variant of this entity is the intramuscular hemangioma, a tumor arising within normal skeletal muscle ; these comprise less than 1 percent (0.89) of all hemangiomas. Most intramuscular hemangiomas occur in the trunk and extremities, where there is larger muscle volume. Approximately 10 percents of the lesions occur in the head and neck region. The management of oral and perioral hemangiomas and the mode of therapy employed depend on several factors including the age of the patient, the size and extent of the lesion, as well as its clinical characteristics. Presented is a case report of intramuscular hemangioma on masseter treated with surgical excision combined with microembolization of feeding vassels, right facial artery.
