title: Ureteral obstruction and hydronephrosis as a complication of lymphomatoid granulomatosis: a case report and literature review.
abstract: Lymphomatoid granulomatosis is an angioinvasive proliferation of atypical T lymphocytes, with frequent pulmonary, cutaneous and neurological manifestations. Urological complications are infrequent. We describe the case of a 40-year-old man who presented with typical intrathoracic findings of lymphomatoid granulomatosis. Following a chemotherapy-induced remission he had retroperitoneal recurrence with bilateral ureteral obstruction, hydronephrosis and renal insufficiency. Histological examination revealed, in addition to the characteristic lymphoid infiltrates of lymphomatoid granulomatosis, a sclerosing process similar to idiopathic retroperitoneal fibrosis.
