The purpose of this paper is to report a case of vascular leiomyoma arose from the maxillary mucolabial fold in a 38-year-old female. Review of the literature revealed 25 cases in Japan and 68 in other countries reported to date.
The patients ranged from infancy to 69 years old and sex ratio was 5:2, with a inclination to males. The clinical appearance of vascular leiomyoma was small, painless, and sessile mass, although painful lesion in the lower extremities. Etiology was presumed to be infection, traumatic force or estrogen influences, etc.
Histopathological examination indicated that this tumor was composed of a tortous mass of blood vesseles between interwinding bundles of smooth muscle.
