title: Extrarenal Wilms' tumour: a review and case report.
abstract: A case of extrarenal nephroblastoma in a girl aged 5 1/2 years is reported. From a review of the few other published instances, it is apparent that extrarenal Wilms' tumours are rare occurrences which present a number of unanswered questions of great theoretical interest, particularly as far as their relation to teratomas is concerned.
