Incidental Diagnosis of Monomorphic Epitheliotropic Intestinal T-Cell Lymphoma: A Case Report

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare, rapidly progressive, primary intestinal T-cell lymphoma. It is most commonly seen in the Asian and Hispanic populations and is usually not related to celiac disease, unlike type I enteropathy associated T-cell lymphoma. The most common site of occurrence is the small intestine. Patients usually present during the advanced stage of disease with clinical features of intestinal perforation or obstruction. The late clinical presentation and lack of targeted therapy are factors contributing to its poor prognosis. Here, we are presenting the case of a patient who initially came to the hospital for a urinary tract infection. As his abdominal CT scan showed abdominal wall thickening, he underwent further workup which revealed the diagnosis of MEITL.
