BLADDER - Stones

Considerably enlarged bladder showing marked trabeculation of posterior surface; a large diverticululm is seen on right-hand side of specimen. On undersurface a part of a considerably enlarged prostate can be seen. Caclui is present in bladder; the display of these is under Pathologists' licence as, infact, the stones were found in diverticulum.
Elderly man found dead at home; he had been treated for an acute bronchitis. At autopsy found to have right-sided empyema and left-sided pleural effusion, bronchopneumonia and carcinoma of colon. Prostate noted to be enlarged; bladder showed features demonstrated here. Microscopy - metastatic tumour in lung from squamous cell carcinoma; it was assumed this had arisen from one of several probably malignant lesions on his skin.
