Abstract

Lymphoepithelioma-like gastric carcinoma (LELGC) has special clinicopathologic features that differentiate it from the common gastric adenocarcinoma. LELGC is a rare neoplasm of the stomach with an incidence of 1-4% of all gastric cancers and is characterized by desmoplastic stroma uniformaly infiltrated by abundant lymphocytes and plasma cells. LELGC is closely associated with the Epstein-Barr virus (EBV), with 80-100% of LELGC being EBV-positive. LELGC has a male predominance, occurs in elderly people and is usually located in the upper and middle portion of the stomach. We report a rare case of lymphoepithelioma-like gastric carcinoma located in the lesser curvature at the border of the gastric body to the pyloric antrum.

摘要

淋巴上皮瘤样胃癌（LELGC）具有特殊的临床病理特征，使其有别于常见的胃腺癌。LELGC是一种罕见的胃部肿瘤，占所有胃癌的1%-4%，其特征是促纤维组织增生性间质中有大量淋巴细胞和浆细胞均匀浸润。LELGC与爱泼斯坦-巴尔病毒（EBV）密切相关，80%-100%的LELGC为EBV阳性。LELGC以男性居多，好发于老年人，通常位于胃的中上段。我们报告一例罕见的位于胃体与幽门窦交界处小弯侧的淋巴上皮瘤样胃癌。
