A case of angiomyoma of the lower lip
2001
An angiomyoma is a benign tumor usually located in the lower extremities of middle aged. women. It is rarely found in the oral region. We report the clinical features and immunohistochemical findings of angiomyoma arising in the lower lip of a 51-year-old man. He was referred to our clinic because of a painless mass in the lower lip. The tumor measured about 10×10mm and was a localized, elastic soft, mucosal swelling of the lower lip. The tumor was resected. Microscopically, the tumor consisted of masses of leiomyoma and endothelial cells. The immunohistochemical analysis showed positive reactions for desmin and HHF-35 in angioendothelial cells and in most of the tumor cells. The histopathological diagnosis was angiomyoma.
