涎腺恶性淋巴上皮病损的临床病理研究

涎腺恶性淋巴上皮病损是涎腺罕见的恶性肿瘤之一，具有明显的种族特性。本文对２７例恶性淋巴上皮病损进行了临床病理学分析和随访调查，探讨肿瘤生物学行为有关的病理因素，发现间质中纤维结缔组织多，玻璃样变明显者预后较差，本文还着重对ＭＬＥＬ的命名、诊断、鉴别诊断、病理组织学与预后的关系进行了讨论。

Malignant Lymphoepithelial Lesion of the Salivary Glands

Malignant lymphoepithelial lesions of the salivary glands are rare but occur more often in Southern Chinese and North American Inuit. 27 cases of MLEL are reported.19 of which got follow-up imformation. The results of comparative analysis between pathological indexes and biological behavior suggested that the cases with rich fibrous stroma and excessive hyalinazation of stroma had worse prognosis. The nomenclature, dignosis, differential dignosis and the relationship between pathologic features and prognosis were also discussed.
