“…2,3 Angioleiomyomas of the oral cavity are rare, the lips are most frequent site, followed by the palate, mucosa of the cheek, and tongue. [4][5][6] Generally, patients diagnosed with angioleiomyoma are middle-aged adults and it has a preference for males.…”

Angioleiomyoma is a benign neoplasm that was considered a tumor of smooth-muscle origin until the most recent (2013) WHO classification of soft tissue tumors, in which it was reclassified as a tumor of perivascular origin. Angioleiomyomas rarely occur in the oral cavity. These lesions are treated surgically with good prognosis. This article presents a review of reports of oral angioleiomyoma in the literature from the last 5 years and describes the case of a 44-year-old man who presented with an asymptomatic nodule in the upper lip that had developed over a 6-month period. Diagnostic hypotheses of pleomorphic adenoma or canalicular adenoma were raised. Biopsy of the lesion, histopathological and immunohistochemical analysis (S100, CD34, H-caldesmon, and desmin) confirmed a diagnosis of angioleiomyoma. It is noteworthy that immunohistochemistry is an important auxiliary method for differential diagnosis of angioleiomyoma from other tumors, particularly myopericytoma.Keywords: angioleiomyoma; diagnoses; immunohistochemistry. ResumoO angioleiomioma é uma neoplasia benigna que, a partir da nova classificação da OMS (2013) para os tumores de tecidos moles, deixou de ser considerado um tumor de origem muscular lisa, passando a ser considerado um tumor de origem perivascular. Raramente os angioleiomiomas ocorrem na cavidade oral. A lesão é tratada cirurgicamente, com prognóstico considerado favorável. Este trabalho revisa os casos de angioleiomioma oral relatados na literatura nos últimos 5 anos e descreve esse tumor em um homem de 44 anos que apresentou um nódulo assintomático localizado em lábio superior, com evolução de 6 meses. As hipóteses diagnósticas foram de adenoma pleomórfico e adenoma canalicular. A lesão foi submetida a biópsia e análise histopatológica e imuno-histoquímica (S100, CD34, α-SMA, H-caldesmon e desmina) confirmaram o diagnóstico de angioleiomioma. Destacamos a imuno-histoquímica como um importante método auxiliar no diagnóstico diferencial do angioleiomioma com outras lesões e, principalmente, com o miopericitoma.Palavras-chave: angioleiomioma; diagnóstico; imuno-histoquímica.

“…Angioleiomyoma development is believed to be triggered mainly by warming stimulus or mechanical trauma, venous stasis, and hormonal changes (4,5). We experienced one case of angioleiomyoma, in a 45-yearold man, the age and sex in which angioleiomyoma is more common.…”

“…These exact results were obtained in our case. Minor trauma, venous stasis, and hormonal changes have been suggested as etiological factors of AL [3,4]. The roles of estrogen and progesterone have been particularly emphasized, and the presence of PRs and ERs has been evaluated in some previous studies.…”

“…For this reason, immunohistochemical analysis is very helpful in making the definitive diagnosis. Staining for SMA, HHF-35 actin, vimentin, desmin, and S-100 protein has assisted in the diagnosis in many cases as an adjunct to H&E staining [2,4,[6][7][8][9]. The presence of SMA is especially useful for confirming smooth muscle origin of the tumor cells.…”

Angioleiomyoma (AL) is a benign tumor derived from smooth muscle. The overwhelming majority of ALs occur in the uterus, gastrointestinal tract, or skin; AL of the oral cavity is infrequent, and AL of the tongue is particularly rare. The present report describes a case of AL of the tongue that resulted in a good outcome. We also review the literature with a special emphasis on the etiology of ALs. It is generally agreed that minor trauma, venous stasis, and hormonal changes are etiological factors for AL. The roles of estrogen and progesterone have been particularly emphasized, and the expression of progesterone receptors (PRs) and estrogen receptors (ERs) has been recently evaluated in some cases of AL. To our knowledge, the presence of PRs and ERs has only been evaluated in seven cases of AL arising in different regions of the body including the oral cavity. This is the first report to demonstrate negative expression of both receptors in an AL of the oral cavity. Further study and additional cases are needed to elucidate the influence of PRs and ERs in AL of the oral cavity.
