BLADDER - Carcinoma

This specimen is difficult to orientate; there is a large tumour mass which in fact is projecting into a diverticulum of the bladder; part of the diverticulum can be seen above and a cuff of bladder mucosa is apparent around the base of the lesion. The tumour is infiltrating bladder wall and originally measured 6 x 5 x 5 cm. The serosal fibro-fatty tissue does not appear to be infiltrated by tumour.
This man presented at the age of 62 with an episode of haematuria. Microscopically the tumour is a Grade III transitional cell carcinoma. The lymph nodes removed from the specimen were not infiltrated by tumour.
