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

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 x 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.
