title: [Ormond's fibrosis, bone osteolysis and stomach intramural metastases in the course f low-differentiated prostatic cancer].
abstract: Retroperitoneal fibrosis (Ormond's disease) is rare chronic inflammatory process, that can occur at any age. It is characterised by development of periaortic fibrous mass leading to progressive obstruction of vessels around the abdominal aorta and ureters. In the one third of cases we can find the causes of disease. There are ergotamine abuse, radiation, retroperitoneal surgery or hemorrhage, urine extravasation and response to different cancers. The other cases are idiopathic disease. We report a case of prostate cancer with unique course. The first manifestations of disease were diffuse peritoneal fibrosis and ureteral obstruction leading to bilateral hydronephrosis. Clinical course and histopathology showed idiopathic Ormond's fibrosis. Patient received oral immunosuppressive treatment (prednisolone 1 mg/kg/day + azathioprine 1 mg/kg/day), followed by intravenous methylprednisolone puls (2 g). Treatment also consisted of DJ-stent placement on the left side. On the right side we were unable to overcome the obstruction of ureter. Because of persistent renal failure, thrombocytopenia, DIC and progressive lower back pain we did control MR and CT scan. The CT scans showed multiple osteolytic bone metastases in vertebral column (the sizes of them were between a few millimetres and 1.5 centimetre). Patient died due to renal failure and haemorrhagic diathesis in the course of disseminated cancer of unknown origin. The postmortem examination revealed diffuse peritoneal infiltration surrounding the ureters, intramural ventricular metastases, pulmonary metastases and vertebral metastases. The prostate was only slightly enlarged. Histological and immunohistochemical examinations of prostate showed primary low-differentiated prostate carcinoma (CK/+/, PAP/+/, PSA/+/). Peritoneal, ventricular and bone infiltrations also were metastases from low-differentiated carcinoma of prostate origin (CK/+/, PAP/+/, PSA/-/).
