Multiple lymphomatous polyposis with diffuse involvement of the gastrointestinal tract. Case report

The gastrointestinal tract is the predominant site of extranodal non-Hodgkin lymphomas. Multiple lynphomatous polyposis is a type of appearance of mantle cell lymphoma. It is characterized by multiple polypoid lesions involving long gastrointestinal tracts and it accounts for only approximately 1-2% of non-Hodgkin lymphomas. A 78 years old patient was admitted to our Department of General Surgery with rectal bleeding, abdominal pain and weight loss. Multiple lymphomatous polyposis was detected by endoscopy. Endoscopic biopsies confirmed the diagnosis of mantle cell lymphoma. The patient was transferred to the Department of Hematology for cycles of chemotherapy.
