“…9 These tumors appear to arise from the tunica media of small vessels, from arteriovenous anastomoses, or the smooth muscle cells of the circumvallate papillae of the tongue. 5,12 Although the lips are described as the most common site of angioleiomyomas within the oral cavity, [4][5][6] according to reports in the specialized literature published over the last 5 years (summarized in Table 2), the gingiva was the most common anatomical site in 29.4% of cases.…”

“…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. 4,7,8 Clinically, oral angioleiomyoma is characterized as a submucosal nodule, with a firm consistency, slow growth and, in the majority of cases, a size of 2 cm in diameter or less.…”

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.

“…It frequently occurs in the female genital tract and lower extremities, with skin and stomach being less commonly affected. The head and neck region lack smooth muscle; therefore the occurrence of VL in this area is extremely rare, accounting for less than 1% of all lesions (1)(2)(3)(4)(5). The most frequent locations in the oral cavity are the lips and the tongue (4)(5)(6)(7).…”

Vascular Leiomyoma (VL) is a benign soft tissue tumor rarely observed in oral tissues. The aim of this paper is to present a new case of vascular leiomyoma of the lip (VLL), describing its clinical, microscopical, and immunohistochemical features, and review the literature on the tumor. A 27-year-old woman presented with a small painful lesion on lower lip mucosa. Excisional biopsy revealed a well-circumscribed, encapsulated mass formed by small and fusiform cells. Immunohistochemistry analysis revealed intense and diffuse expression of smooth muscle actin (SMA) within the tumor cells and CD34 immunoreactivity of the endothelial cells lining the vascular spaces, indicating the presence of blood vessels. A final diagnosis of VLL was established. No signs of recurrence were observed after five years of follow-up. Although VLL is a rare lesion, it must be considered in the differential diagnosis of nodular lesions on lower and upper lips.

This study presents a case of an oral angioleiomyoma along with its clinical diagnostic approach and laboratory confirmation. The differential diagnosis, especially from angioleiomyosarcoma, is also included. A 51-year-old patient presented with a tumor-like lesion on his upper labial mucosa. The clinical examination revealed a benign lesion that was surgically removed. Histopathological and immunohistochemical examinations confirmed the diagnosis of an oral angioleiomyoma. The post-surgical period was uneventful. No recurrence had occurred after a year of follow-up surveillance. Oral angioleiomyoma is a very rarely occurring oral lesion. Clinically, it may mimic some benign lesions, including fibroma, pyogenic granuloma or minor salivary gland tumor. Surgical excision is the treatment of choice. Histological and immunohistochemical examination can confirm the diagnosis. The differential diagnosis is crucial to rule out angioleiomyosarcoma.
