    Figure 2 Esophagogastroduodenoscopy demonstrated an ulcerated, infiltrating lesion which occupied 50 % of the lumen in the third part of the duodenum.

    Figure 3 Histological examination of the duodenal biopsy revealed a true natural killer-cell lymphoma, with transmural infiltration of large pleomorphic cells. These cells were CD56-positive (Anti-CD56; Santa Cruz Biotechnology Inc., Santa Cruz, California, USA; × 400), but did not express surface CD3 or T-cell lineage.
