Abstract：
Pleomorphic adenomas (PA) are the most prevalent benign salivary gland neoplasms. They may occur at any age, with a peak incidence between 40 and 60 years of age. They are more commonly observed in females (60%). These tumors can arise in both the major and minor salivary glands. Approximately 80% of these tumors are diagnosed in the parotid gland, whereas 10% arise in the minor salivary glands, mainly affecting the palates, followed by the lips and cheeks. This report describes two cases of unusual lesions that were diagnosed as (PA) in the minor salivary glands in our department via a review of the relevant literature. The first case involved an 83-year-old man who presented with a slow-growing swelling on the right side of the upper lip, and the second case involved a 45-year-old woman who presented with a slow-growing lesion on the palate. The presence of PA was confirmed histopathologically after surgical resection. Although relatively rare, PA is a benign lesion, the diagnosis of which must be known for appropriate therapeutic management.
摘要：
多形性腺瘤（PA）是最常见的良性唾液腺肿瘤。它们可能发生在任何年龄，发病率在40到60岁之间。在女性中更常见（60％）。这些肿瘤可以出现在主要和次要唾液腺。这些肿瘤中约有80％被诊断为腮腺，而10%出现在小唾液腺，主要影响味觉,其次是嘴唇和脸颊。本报告通过回顾相关文献，描述了两例在我科的小唾液腺中被诊断为（PA）的异常病变。第一例涉及一名83岁的男子，他的上唇右侧出现缓慢增长的肿胀，第二例涉及一名45岁的妇女，她的上颚有缓慢生长的病变。手术切除后在组织病理学上证实了PA的存在。虽然相对罕见，PA是良性病变,对于适当的治疗管理，必须知道其诊断。
