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.

Nasopharyngeal carcinoma (NPC), historically termed 'lymphoepithelioma-like carcinoma' due to its rich lymphocyte infiltration, benefit from PD-1 blockade treatment. However, a comprehensive understanding of its tumor microenvironment (TME) remains elusive, hindering the identification of effective biomarkers for immunotherapy. We leveraged multimodal profiling data, including gene expression, immunohistochemistry, and multiplex immunohistochemistry, from three independent cohorts of NPC patients with a total of 327 patients to dissect the TME in NPC.

Background: Epstein-Barr virus (EBV) is a double-stranded DNA oncogenic virus. Several types of solid tumors, such as nasopharyngeal carcinoma, EBV-associated gastric carcinoma, and lymphoepithelioma-like carcinoma of the lung, have been linked to EBV infection. Currently, several TCR-T-cell therapies for EBV-associated tumors are in clinical trials, but due to the suppressive immune microenvironment of solid tumors, the clinical application of TCR-T-cell therapy for EBV-associated solid tumors is limited.
