多形性腺瘤(PA)是唾液腺最常见的良性病变之一,其中大部分发生在腮腺。PA起源于上皮和间充质元件,可以来自主要和次要唾液腺。在小唾液腺中,腭是最常受影响的部位,接着是嘴唇,脸颊,牙龈,嘴巴的地板,和舌头。没有口腔内粘膜受累的上唇PA是一种罕见的实体。在这篇文章中,我们报告了一例中年女性患者上唇PA的病例,并采用了一种新技术对其进行了手术治疗。术后6个月复查,患者表现出良好的伤口愈合,疤痕形成很少。
Pleomorphic adenoma (PA) is one of the most common benign lesions of the salivary glands, with a majority of them occurring in the parotid gland. PA has origin from the epithelial and mesenchymal elements and can arise from both major and minor salivary glands. Among minor salivary glands, the palate is the most commonly affected site, followed by lips, cheeks, gingiva, the floor of the mouth, and tongue. PA of the upper lip without intraoral mucosal involvement is a rare entity. In this article, we report a case of PA of the upper lip in a middle-aged female patient and its surgical management with a novel technique. During six months\' postoperative review, the patient showed excellent wound healing with very minimal scar formation.
