Plasmablastic Lymphoma Causing Adult Intussusception After Cardiac Transplantation.

Intussusception in adults is a rare occurrence at approximately 5% and malignancy as the cause comprises half that number. The most common malignancies found are primary adenocarcinoma, metastatic carcinoma, lymphoma, and gastrointestinal stromal tumors. Lymphoma is the second most common. The management of adult intussusception is generally surgical, which is due to the higher likelihood of malignancy being the underlying cause. The patient's history helps to direct management and the most likely underlying diagnosis. This is especially important in patients who are immunosuppressed and with a history of lymphoproliferative disease. Early management and proper surgical intervention allow for the best survival rate. Here we present a case of adult intussusception caused by a rare and aggressive type of non-Hodgkin lymphoma.
