An unusual presentation of non-hodgkin's lymphoma

Abstract

Non-Hodgkin's lymphoma (NHL) causes many deaths worldwide. It represents a heterogeneous group of neoplasms originating from the lymphocytes. The etiology of this disease is still unclear. Some infectious agents have been associated more or less strictly with the development of an NHL as, i.e., the Epstein–Barr virus, the human herpesvirus-8, and the human T-cell lymphotropic virus Type I. Nearly 70% of lymphomas present a generally multilocalized, single, or multiple lymphoadenomegaly without pain, with involvement in almost 30%–40% of laterocervical lymphnodes. In 30% of patients, an extranodal localization is reported in Waldeyer's ring, in the stomach, and generally, in the gastrointestinal tract. The retroperitoneal localization is extremely rare and its diagnosis is often difficult. It often requires a time-consuming and costly diagnostic workup. Here, we present a rare case of NHL presented with retroperitoneal mass encasing the aorta.
