RESUMO
The authors report the case of a 70-year-old woman with a mesenteric tumor, apparently isolated. Histologic examination led to the diagnosis of lymphomatoid granulomatosis. A review of the literature found four previously published cases of lymphomatoid granulomatosis with mesenteric localization, and with or without pulmonary involvement. The general features of this affection are recalled. Special attention is given to forms without pulmonary involvement (Liebow granulomatosis) as well as to their relationship with polymorphic reticulosis. Separation of these two disorders, which depended mainly on a strict distribution of the various lesions, seems questionable. The authors tend to consider that both conditions belong to the same nosologic group, sincea pathological features are similar and borderline cases exist.
