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

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.
