Core Tip	This case highlights an important clinical message: Mantle cell lymphoma should be included in the differential diagnosis of rectal bleeding when endoscopic findings resemble ulcerative colitis or proctitis. Awareness of this rare presentation may facilitate earlier diagnosis and appropriate oncologic management. Given the rarity of gastrointestinal involvement, particularly at the rectal level, prospective studies are needed to better define optimal therapeutic strategies and improve clinical outcomes in this subset of patients.
