摘　　要：BACKGROUND Gastrointestinal lymphoma typically arises in the stomach,small bowel,or colorectum and is usually a B-cell lymphoma.However,primary T-cell lymp-homas originating in the stomach are particularly rare.Gastric peripheral T-cell lymphoma-not otherwise specified(PTCL-NOS)is an extremely rare subtype.CASE SUMMARY We report a 63-year-old male presenting with epigastric pain.Esophagogastro-duodenoscopy revealed a large ulcerative lesion in the gastric cardia.Biopsy and immunohistochemical profiling confirmed PTCL-NOS.Imaging indicated stage II disease involving the stomach and intra-abdominal lymph nodes.The patient is planned to undergo cyclophosphamide,doxorubicin,vincristine,and prednisone or cyclophosphamide,doxorubicin,vincristine,prednisone,and etoposide chemo-therapy.CONCLUSION This case highlights the necessity of considering PTCL-NOS in differential diag-noses of gastric lesions.Comprehensive histopathological and immunohistoche-mical analysis is crucial for accurate diagnosis and guiding treatment.
