[A Case of Mantle Cell Lymphoma Diagnosed after Surgery for Ileocecal Intussusception]

A 63-year-old woman visited our hospital complaining of abdominal pain and bloody discharge in November 2015. Abdominal CT revealed ileocecal intussusception. After hospitalization, a right colectomy was performed. Pathological diagnosis of the resected specimen was Mantle cell lymphoma. After this diagnosis, chemotherapy was initially administered. Following this, peripheral stem cell transplantation was carried out. We discovered this case of Mantle cell lymphoma by chance; therefore, here, we consider and introduce how this type of disease should be treated. We also introduce a rare case of Mantle cell lymphoma with intussusception at the cecum.
