DISSEMINATED INFLAMMATORY PSEUDOTUMOR OF THE LYMPH-NODES

Inflammatory pseudotumour of lymph nodes is a benign type of lymphaden opathy recently described as a peculiar nodal reaction, which displays distinctive clinical and histological features. The origin of the dis ease is unknown although an inflammatory etiology has been suggested. We study a new case of inflammatory pseudotumour of lymph nodes which had an unusual clinical presentation, with lymphadenopathy on both sid es of the diaphragm and enlargement of liver and spleen. In addition, focal fibrinoid vascular necrosis was observed on histological examina tion, an unusual finding which makes difficult the differential diagno sis with other lesions, particularly vasculitis.
