Angioleiomyoma is a rare, benign tumor often found in the uterine myometrium, gastrointestinal tract, and skin and seldom observed in the oral and maxillofacial region. The most common site of occurrence in the oral cavity is the lip, followed by the palate, buccal mucosa, and tongue. The number of reports associated with angioleiomyoma arising from the hard palate is very small. The tumor is histologically characterized by the proliferation of mature smooth muscle cells and numerous blood vessels. When the diagnosis is difficult, specific immunohistochemistry is used. This report describes a case of angioleiomyoma in which there was a chronically increasing lesion for 5 years on the left hard palate and the means for making a definitive diagnosis was based on previous reports on angioleiomyoma of the palate.
血管平滑肌瘤是一种罕见的良性肿瘤，常见于子宫肌层、胃肠道和皮肤，在口腔颌面部区域很少见。口腔中最常见的发病部位是唇部，其次是腭部、颊黏膜和舌部。关于硬腭起源的血管平滑肌瘤的报道数量非常少。该肿瘤在组织学上的特征是成熟平滑肌细胞和大量血管的增殖。当诊断困难时，会使用特异性免疫组织化学方法。本报告描述了一例血管平滑肌瘤病例，该病例在左侧硬腭有一个持续增大5年的病变，确诊方法基于以往关于腭部血管平滑肌瘤的报道。
