Adult Wilms' tumour; a case report with review of literature

Abstract

Background: Wilms' tumor is the commonest primary malignant renal tumor in childhood. Rarely, it may present in the adult age group. Case presentation: We report a 48-year-old male presenting with flank pain and haematuria. Abdominal ultrasound revealed a right renal mass measuring 11 × 10 cms, and a clinical diagnosis of renal cell carcinoma was made. Nephrectomy was performed, and a final diagnosis of adult Wilms' tumor was made based on the criteria proposed by Kilton et al. Conclusion: The possibility of an adult Wilms' tumor should be considered when a patient presents with pain in the flank and a renal mass. Rarity of the tumor favors documentation in literature.
