title: Mantle cell lymphoma with multiple lymphomatous polyposis and intussusception: A case report.
abstract: Mantle cell lymphoma (MCL) is a rare malignant lymphoma of the gastrointestinal (GI) tract that may present as multiple lymphomatous polyposis (MLP); however, MLP with intussusception is rarely reported in MCL. In the present study, a 54-year-old male patient was diagnosed with MCL, presenting with numerous polypoid lesions of the complete GI tract combined with ileocecal intussusception. Right hemicolectomy was performed in order to prevent complicated intussusception and for tumor debulking. In addition, 6 cycles of chemotherapy were performed with the rituximab plus hyper-CVAD regimen. Subsequent to the planned chemotherapy cycles, follow-up examination demonstrated a complete response and the remission lasted for 3 years until the present time.
