title: Adult Wilms' tumor: report of a case and review of the literature.
abstract: A 48 year old male presented with a one and a half year history of a progressively increasing, asymptomatic lump in the left hypochondrium and no history of hematuria. His general physical examination was unremarkable, and an abdominal examination revealed a large, firm, irregular and tender mass in the left hypochondrium extending into the lumbar region. Chest X-ray was normal. An intravenous urogram revealed a normally functioning right kidney with non-visualization of the left kidney. CT-scan of the abdomen revealed a large, mixed attenuating mass replacing the left kidney. At laparotomy, a large, fleshy, well-encapsulated tumor was found in the left kidney with no surrounding infiltration and a left radical nephrectomy was performed. Microscopic examination revealed a poorly differentiated tumor comprised of small round cells with focal areas of abortive embryonal tubular and glomerular differentiation suggestive of Wilms' tumor. The patient was advised chemotherapy and radiotherapy but he absconded and was lost to follow-up.
