Abstract
Introduction: Leiomyomas are benign smooth muscle neoplasms that preferably affect the genitals, skin, and gastrointestinal tract, being rarely seen in the oral cavity. They re commonly classified into three microscopic patterns: solid leiomyoma, angioleiomyoma (ALM), and epithelioid leiomyoma. The most frequently reported sites of occurrence of oral ALM are the lip (48.6%), palate (21.1%), buccal mucosa and tongue (9.2%), and intraosseous lesions (8.3%).Case report: A 62 years old male presented a painless swelling in the left cheek. In this report histopathological and immunohistochemical analysis were made to confirm the diagnosis, since several lesions were possible. The treatment was local surgical excision of the tumor.

Summary
Histoquímicos e imunoistoquímicos de angioleiomioma de mucosa jugal: relato de caso Leiomyomas are benign smooth muscle neoplasms that preferably affect the genitals, skin, and gastrointestinal tract, being rarely seen in the oral cavity. ALM accounts for about two thirds of all benign smooth muscle tumors of the oral cavity and exhibits prominent vascular channels. Regarding the origin of oral cavity leiomyomas, it has been proposed that these tumors arise from vascular smooth muscle [2].
