Angioleiomyoma of the upper lip

Clinical, Imaging and Histopathology of Angioleiomyoma of the Buccal Cheek

Angioleiomyoma is a benign neoplasia originating from vascular smooth muscle and very uncommon in the oral cavity. In this report, we present a rare case of angioleiomyoma in oral cavity in a 46-year-old female buccal cheek and discuss the clinical, histological, and immunohistochemical characteristics. As the treatment of choice is the complete excision, the lesion was excised under local anesthesia with no further complications. In addition, a brief update on other reported cases of angiomyoma in the oral cavity is further discussed.

Clinical and Immunohistochemical Features of Oral Angioleiomyoma: A Comprehensive Review of the Literature and Report of a Case in a Young Patient

Angioleiomyoma (AL) is an uncommon benign soft tissue neoplasia arising from the tunica media of the smooth muscle cells. AL appears as a solitary and slow-growing mass and seldom is observed in oral tissues. We reported a rare case of AL involving the cheek of a 17-year-old young woman. A review of the English-language literature was performed entering the keywords “angioleiomyoma” and “oral” in the search fields of PubMed. 70 results were identified. Excluded were cases that were not in the oral cavity or not compatible with the AL diagnosis or report lacking immunohistochemical analysis. According to the exclusion criteria, we selected 30 studies that included 63 cases of AL. The results of the review showed an average age of 42.97 years with a prevalence between the fourth and fifth decade of life with a male-to-female ratio of 1.95 : 1. The most affected sites were palate, buccal mucosa of the cheek, lip, tongue, and gingiva. Surgical excision was the treatment of choice, and diagnosis was possible through histopathological and immunohistochemical analysis. SMA, vimentin, CD34, desmin, and S-100 were the most common markers to guide the histopathological diagnosis of oral AL. In conclusion, oral AL is a rare entity, especially in adolescence as in the reported case of AL of the cheek in a 17-year-old woman. The clinical aspects of AL did not allow clinicians to make a correct presumptive diagnosis. A scrupulous histopathological analysis and immunohistochemical examinations are fundamental to differentiate AL from other lesions.

Angioleiomyoma of the oral cavity: a case report and brief review of the literature

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.
