The Wilms' tumour is a solid childhood tumour of the kidney, consisting of blastema, tubules and mesenchyme. Embryonic tumours, such as Wilms', may arise as a result of a developmental disturbance in differentiation. The expression of class I and II major histocompatibility complex (MHC) antigens was investigated on 6 Wilms' tumours and related to that in… (More)

FINDINGS The majority… (More)
Reactivity of the monoclonal antibody 791T/36 with secondary malignant deposits has been investigated in frozen sections of 74 human liver biopsy specimens. There was no reactivity with hepatocytes but in some instances binding to fibrous tissues and in one case to portal tract lymphocytes was observed. Sections from 9 biopsy specimens contained malignant… (More)
