Abstract
Malignant lymphoma in colorectal location represents a rare involvement and very exceptional reason for elective surgery. The case of mantle cell lymphoma - mantle cell lymphoma-MCL, even with caecal and rectal involvement has been described and progressed on despite several previous chemotherapy regiments.
Rectal lesion caused rectal syndrome and was the reason for surgery. All intestinal symptoms disappeared at once after resection of rectum (and right colectomy).
The case report reminds of important aspects of multimodal treatment and stress the role of surgery in special cases.
