RESUMO
The aim of this study was to examine a case report of vascular leiomyoma located in the oral mucosa of the oral cavity. Vascular leiomyoma is a benign tumor arising from smooth muscle. One factor that makes vascular leiomyomas in the oral cavity rare is that there is little smooth muscle in the mouth. The most common histological subtype in the oral cavity is the vascular subtype. The greatest difficulty in histological diagnosis of this entity is the similarity in morphology with other malignancies, particularly of neural or fibroblastic lineage. Wide surgical resection is the only treatment reported in the literature with good results. The recurrence rate is very low if complete resection is achieved. The study of rare or unusual lesions is very important for the clinical diagnosis of vascular leiomyoma.
