The bladder had been opened from above to show a nodular mass at the base of the bladder leading
down into the urethra. On the reverse of the specimen the outline of the prostate can be seen with
tumour tissue infiltrating the bladder.
This was an incidental finding in a man aged 66 who was found dead in bed; death was
attributed to coronary artery disease. At autopsy the prostate was found replaced by tumour and
extending into the base of the bladder, producing ureteric blockage with dilatation of the ureters.
Microscopy showed a moderately well differentiated andenocarcinoma of the prostate; there was
infiltration by tumour in the lung and the mediastinal lymph nodes were involved.
