Colon Involvement in Non Hodgkin Lymphoma References

Gastrointestinal tract involvement in non-Hodgkin lymphoma (NHL) varies greatly and is rather rare. Involvement of the gastrointestinal tract in mantle cell lymphoma, by way of contrast, may be 100%, according to some American authors. Lymphoma infiltrates in the colon are often very numerous leading to confusion with FAP. The surface of lymphoid polyps is, however, often very smooth, sometimes demonstrating a typical starlike vessel pattern. The mostly broad-based polypoid structures are paler than the unaffected colon mucosa. Larger polyps can present as stalked villous adenomas (Fig. 17.18).
