title: Retroperitoneal fibrosis secondary to metastatic neoplasm.
abstract: Retroperitoneal fibrosis may occur secondary to metastatic neoplasm and may simulate the features of the idiopathic variety. A case of retroperitoneal fibrosis due to gastric carcinoma is presented and the historical, physical, cystoscopic, urographic, operative, and pathologic similarities to the idiopathic form discussed. Generous biopsy of retroperitoneal plaques and careful pathologic examination are stressed to avoid missing malignant disease.
