Quadruple renal neoplasia: bilateral renal tumors of dissimilar histogenesis.
Four separate renal neoplasms were removed from a 64-year-old man during a period of 8 months. A lesion was first identified in the left kidney and the nephrectomy specimen had 2 separate adenocarcinomas. A third adenocarcinoma and a papillary urothelial pelvic carcinoma were found subsequently and segmentally resected from the right kidney. The patient died 9 years later with local recurrence of the urothelial neoplasm but no evidence of metastatic carcinoma.
