[Efficacy of rituximab in lymphomatoid granulomatosis].

Introduction: Lymphomatoid Granulomatosis is a rare and serious disease, now considered to be a B-cell lymphoma, which is frequently associated with Epstein-Barr virus infection. There is no consensus on treatment, which is usually based on steroid therapy, either alone or combined with cyclophosphamide and combination chemotherapy.

Case Report: We report the case of an asymptomatic patient diagnosed after the incidental discovery of bilateral nodular opacities on their chest x-ray.
