Successful management of adult lymphoma-associated intussusception by laparoscopic reduction and appendectomy

Figure 1 Contrast-enhanced computed tomography showed a well-defined homogeneous mass (asterisk) in the mesenteric root region, together with a long segmental wall thickening in the ileum with ileocolic-type intussusception (arrow).

Figure 2 Invagination of the terminal ileum into the proximal colon.

Figure 3 Histological and immunohistological examination of the specimens showing diffuse large B-cell non-Hodgkin's lymphoma. A: Magnification × 20; HE staining. Tumor cell infiltrates can be observed in the serosal layer of the appendix; B: Magnification × 400, HE staining, polymorphic large B cells; C: Magnification × 400, CD20(+); D: Magnification × 400, Bcl-2(+). Bcl-2: B-cell lymphoma 2; HE: Hematoxylin and eosin.
