Most of these tumors are located in the cecal area. Surgery is the most widely utilized form of therapy. Although adjuvant therapy is frequently utilized, its' impact on survival is unclear.

Splenic Flexure Diffuse Large B Cell Lymphoma With Bowel Obstruction: A Radio Pathological Correlation

Despite the severe luminal narrowing, lymphoma is less likely to cause obstruction because it does not elicit a desmoplastic response and submucosal lymphoid infiltration weakens the muscularis propria of the wall.…”

Primäres Hodgkin-Lymphom des Kolons

“…Primäre Lymphome des Kolons sind hingegen eine Seltenheit. In 2 nahezu zeitgleich erfolgten Analysen größerer Kohorten ergab sich ein Anteil der malignen Lymphome unter allen untersuchten Kolonneoplasien von lediglich 0,9 [4] bzw. 0,48% [5].…”
