A Case of Epstein-Barr Virus-associated Primary Gastric T-cell Lymphoma with Rapidly Progressive Endoscopic Features and Clinical Course / 대한소화기내시경학회지

Primary gastric T-cell lymphoma is very rare. Only a few cases have been reported in the literature. Moreover, Epstein-Barr virus-associated primary gastric T-cell lymphoma is extremely rare. We report a case of Epstein-Barr virus-associated primary gastric T-cell lymphoma, which showed rapidly progressive endoscopic features. Three esophagogastroduodenoscopic examinations in a 26-day period revealed different findings at different locations. The lymphoma cells were positive for UCHL-1, but negative for L26 and Ki-1 in immunohistochemical staining.
