Adult Wilms' tumour. A case report with immunohistochemical studies.

Abstract

The case of a 27-year-old female patient presenting with a Wilms' tumour is reported. The tumour was dominantly of blastemal type showing minor epithelial (tubular) areas and anaplastic portions. Thorough immunohistochemical examinations were performed to solve differential diagnostic problems. Keratin positivity was found to be of differential diagnostic value in the distinction of this tumour from the so called small round cell tumours. Prognostic aspects of Wilms' tumour are also discussed.
