Lymphoepithelial cysts are uncommon benign lesions that present as painless yellowish nodules arising from various sites in the oral cavity and other parts of the body. Their etiopathogenesis is controversial, but most authors have assumed that they develop from obstruction of crypts in oral lymphoid aggregates, thus they are not true cysts but pseudocysts of retention. This paper describes a case of a large lymphoepithelial cyst located in the tonsil of a 21-year-old man complaining of a lump in the throat for four months. The patient underwent excisional biopsy, and the histopathological features showed squamous epithelium surrounded by lymphoid tissue, which were characteristically consistent with a lymphoepithelial cyst. We discuss the etiopathogenesis of these lesions and treatment modalities, which can consist of conservative surgery or only follow-up examination.
淋巴上皮囊肿是一种罕见的良性病变，表现为口腔及身体其他部位出现的无痛性淡黄色结节。其发病机制存在争议，但大多数作者认为它们是由口腔淋巴组织隐窝阻塞发展而来，因此它们并非真正的囊肿，而是潴留性假性囊肿。本文描述了一例位于一名21岁男性扁桃体的大型淋巴上皮囊肿病例，该患者主诉咽喉部肿物已4个月。患者接受了切除活检，组织病理学特征显示鳞状上皮被淋巴组织包绕，这与淋巴上皮囊肿的特征性表现一致。我们讨论了这些病变的发病机制及治疗方式，治疗方式可包括保守手术或仅进行随访检查。
