'MAGRO, Alessandra Kuhn-Dall et al. Myoepithelioma preauricular: literature review and case report. RFO UPF [online]. 2014, vol.19, n.2, pp. 218-222. ISSN 1413-4012.

Objective: this work allow to demonstrate by case report and literature review the comportment of benign myoepithelioma. It is considered a rare tumor of the salivary glands, of slow growth, and often asymptomatic, whose incidence is nearly equal between the sexes, may have a slight predilection for women. It can occur in all age groups, being more common around 50 years. The parotid gland and palate are the sites of predilection of this tumor. It can vary from 1 to 5 cm, generally being encapsulated, painless and well delimited, with coloring whitish. The main differential diagnosis of myoepithelioma is the pleomorphic adenoma. Histologically, benign myoepithelioma is composed of myoepithelial cells and treatment consists of surgical removal of the lesion with low rate of recurrence after complete removal. Case report: this work reported a case of benign myoepithelioma located in the preauricular region, removed surgically and followed for eight years without signs of recurrence, as well as the clinical and microscopic characteristics of this disease. Final considerations: although rare, tumors like myoepithelioma can happen in rotine evaluations. Dentists need improve a complete inspection of patient face including all stomatognatic system as soon as adjacent structures by rich semiology criterion. How more precoce the pathology diagnosis more better the prognosis.
