Surgical management of monomorphic epitheliotropic intestinal T-cell lymphoma followed by chemotherapy and stem-cell transplant: A case report and review of the literature

Figure 1  Evolution of classification of monomorphic epitheliotropic intestinal T-cell lymphoma.

Figure 2 Computed tomography images. A: First computed tomography (CT) scan; B: Second CT scan 2 wk later. Multiple enlarged mesenteric lymph nodes and apparent necrosis were noted on the second CT scan.

Figure 3 Pathologic and immunohistochemistry findings. A and B: Low magnification (A) (× 40, H&E) and high magnification (B) (× 200, H&E) images of lymphocytes demonstrating an epitheliotropic pattern; C: The shape of lymphoma cells is uniform throughout, emphasizing the monomorphism; D-H: The tumor cells were positive for CD3 (D), CD8 (E), CD56 (F), Granzyme B (G), and TIA-1 (H). (C-H, magnification × 200).
