case_images: But esophagus and stomach biopsies showed diffuse infiltration of lymphoma cells with epitheliotropic features (Figure 1, 2). The infiltrated lymphoma cells were immunostained for UCHL-1 (+), CD 3 (+), MT-1 (+), L-26 (-) and MB-2 (-) (Figure 1.2.4).
case_images: Gastric biopsy shows diffuse infiltration of lymphoma cells (left) and intraepithelial lymphocytosis are also noted (right).

case_images: Colonoscopic findings were the same as noted previously (Figure 3) and the biopsy showed diffuse infiltration of small to medium-sized lymphoma cells (Figure 4).
case_images: The mucosal architecture of the colon is mostly replaced by medium-sized lymphoma cells (left) that are reactive to CD-3 (right).
