치은에 인접하여 발생한 Masson 혈관종 1예

Masson’s hemangioma, also known as intravascular papillary endothelial hyperplasia, is a benign vascular lesion which is an unusual pattern of organization of a thrombus. It is a solitary slowly growing, often tender, blue to red nodule. Histologically, it is characterized by the development of endothelial-lined papillary projection in a vascular lumen. It usually occurs on the head, neck or extremities. We report the case of 50-year-old man who had such an unusual site on the right mandibular buccal mucosa adjacent to gingiva, which upon histopa- thological examination showed Masson’s hemangioma.
