摘要
对3例口腔淋巴上皮囊肿进行临床病理分析,该囊肿的好发部位为口底,临床上常诊断为黏液腺囊肿等囊性疾病。镜下观察淋巴上皮囊肿以囊壁内衬复层鳞状上皮及纤维囊壁存在大量淋巴样组织为其特点。目前认为,口腔淋巴上皮囊肿可能来源于舌下腺或小唾液腺分泌管。由于慢性刺激,分泌管上皮发生鳞状化生,化生上皮的腔面细胞脱落后引起周围淋巴细胞浸润,表现为淋巴上皮囊肿。本文结合文献进行讨论,为类似病例的预防和诊断提供参考,为临床诊断和治疗提供借鉴。
Three cases with oral lymphoepithelial cyst were reported in this paper. The most frequent site of the cyst was mouth floor, and the cyst was often misdiagnosed as mucous cyst and other diseases of cyst. Histopathologically, the central cystic lesion was lined with stratified squamous epithelium. Simultaneously, there were lymphoid cells located at the surrounding of the cystic fibrous connective tissue. Oral lymphoepithelial cyst was regarded to originate from secretory duct of the sublingual gland and the small salivary gland epithelium. With chronic stimuli, the epithelium of secretory duct was squamous metaplasia. The deciduous cells in the inner side of the duct induced the infiltration of the surrounding lymphocytes. The relevant literatures were reviewed regarding to the histological origin and the pathogenesis of the disease to provide some references for diagnosis and treatment of this disease.
