Mantle Cell Lymphoma Presenting as Cholecystitis and Nephromegaly

Mantle cell lymphoma (MCL) most commonly presents as lymphadenopathy (LAD), fevers, night sweats, weight loss, splenomegaly, and blood count abnormalities. While extranodal involvement as an initial presentation can occur, it is uncommon. At initial diagnosis, MCL most commonly presents as widespread, advanced stage III or IV lymphoma. Given advanced stage MCL at presentation, it is important for medical practitioners to recognize unusual extranodal presentations of MCL for earlier diagnosis and treatment planning. Here, we present a case of MCL initially presenting as cholecystitis and bilateral nephromegaly in a 53-year-old male patient.

Rare presentation of ileocolic intussusception secondary to mantle cell lymphoma

Mantle cell lymphoma is a type of B-cell non-Hodgkin's lymphoma (NHL) and accounts for 3%-6% of all adult NHL.^{1 2} Bowel intussusception secondary to lymphoma is rare in adults, accounting for only 4% of all cases.³The authors present the case of a 53-year-old man, recently diagnosed with mantle cell lymphoma, who presented with sudden onset right-sided abdominal pain and was found to have ileocolic intussusception up to the hepatic flexure on abdominal CT. He underwent an emergency right hemicolectomy and intraoperatively, the terminal ileum could be seen telescoping into the caecum, up to the hepatic flexure. Although intussusception is uncommon in the adult population, an underlying bowel pathology should always be considered and prompt imaging should be organised to confirm the diagnosis and allow initiation of management in a timely manner.
