The lymphoepithelial cyst has been commonly termed branchial cleft cyst or branchial cyst. Although many theories, including the branchial apparatus theory, thymic duct theory, and inclusion theory, have been put forward, the etiology is still controversial. Parotid lymphoepithelial cysts are rare and could be divided into two groups, AIDS-related and non-AIDS related, by the relationship with HIV infection. A non-AIDS related lymphoepithelial cyst of left parotid gland in an 81-year-old man presenting as a parotid tumor is described. A left partial parotidectomy was carried out to remove the lesion. There was no recurrence after 2 years. Lymphoepithelial cysts of the parotid gland are often misdiagnosed as other benign tumors in spite of detailed preoperative investigations. Thus a pathological proof is needed for precise diagnosis. In addition, we also need to take the possibility of HIV infection into consideration, although Taiwan is not an AIDS epidemic area.
淋巴上皮囊肿通常被称为鳃裂囊肿或鳃囊肿。尽管已经提出了许多理论，包括鳃器理论、胸腺管理论和包涵体理论，但病因仍存在争议。腮腺淋巴上皮囊肿罕见，根据与HIV感染的关系可分为艾滋病相关和非艾滋病相关两组。本文描述了一名81岁男性左腮腺非艾滋病相关淋巴上皮囊肿，表现为腮腺肿瘤。行左腮腺部分切除术切除病变。2年后无复发。尽管术前进行了详细检查，但腮腺淋巴上皮囊肿常被误诊为其他良性肿瘤。因此，需要病理证据进行精确诊断。此外，尽管台湾不是艾滋病流行地区，但我们也需要考虑HIV感染的可能性。
