Rhabdoid tumour of the bladder: a histological, ultrastructural and immunohistochemical study

Abstract
A rapidly fatal bladder tumour which had the features of a rhabdoid tumour was studied by sequential biopsies and at autopsy. This is the first rhabdoid tumour recorded at this site and the first in which there was co‐existent transitional cell carcinoma. The possibility that rhabdoid tumour is histogenetically heterogeneous is discussed.
