Angiomyoma

Overview

Angiomyomas are benign smooth muscle tumors that are categorized as a subtype of leiomyomas. They are uncommon in the oral cavity. There are four subtypes of leiomyomas:

• Leiomyoma (simple, conventional, or common), 
• Angiomyoma (angioleiomyoma, vascular leiomyoma),
• Epithelioid leiomyoma (bizarre leiomyoma, leiomyoblastoma) 
• Mesectodermal leiomyoma. 

Regarding the distribution of leiomyomas throughout the body, around 95% of leiomyomas were found in the female vaginal tract, 3% in the skin, and 1% in the gastrointestinal system and other sections of the body. Tumors occur in middle and later age, and while they are somewhat more common in women, gender predominance cannot be verified based on the limited series of head and neck leiomyomas.
