RESUMO
Objective@#To report the first case of lymphomatoid gastropathy in China, and to demonstrate the clinical characteristics, diagnostic approach, treatment and prognosis in this kind of patients.@*Methods@#One patient was diagnosed as lymphomatoid gastropathy at Peking Union Medical College Hospital, and her clinical characteristics, lab data, treatment and follow-up outcomes were reviewed.@*Results@#A case of a 51-year-old female was presented, who underwent esophagogastroduodenoscopy (EGD) due to slight epigastric discomfort. EGD revealed multiple ulcers and erosions. Biopsies showed atypical lymphocytes infiltration with CD3(+), CD56(+), CD20(-), CD8(-), TIA(+), Granzyme B(-) and Ki-67 (75%). Epstein-Barr virus-encoded RNA in situ hybridization was negative. Four months later, repeated EGD examination showed regression of the lesions without specific treatment.@*Conclusion@#Lymphomatoid gastropathy was a unique disease entity mimicking NK/T-cell lymphomas in pathology, with the quite different profile of treatment and prognosis. It’s important to consider this issue during the differential diagnosis to avoid any excessive treatment.
