A computerized tomography (CT) scan suggested the presence of multiple soft-tissue density masses in the patient's abdominal cavity, the largest of which was 7.7 cm x 7.2 cm [Figure 1a and b].

Positron emission tomography-CT (PET-CT) showed that these masses had abnormal 18F-FDG uptake [Figure 2a and b].

We then performed EUS-FNA [Figure 3] to obtain a tissue sample for biopsy.

Then, enucleation of the targeted lymph node was performed using an IT knife [Figure 5].
Immunohistochemical staining: CD3(large cell-); Vimentin(+); PAX-5(-); CD15(-); CD20(large cell+); CD21(+); Ki-67(large cell8%+); CD30(-); CD68(partly+); CK(-); MUM-1(-); CD10(-); Bcl-6(+); Bcl-2(+). The diagnosis was non-Hodgkin lymphoma, germinal center B-cell-like diffuse large B-cell lymphoma
