The urinary bladder stores urine until one has to go wee-wee.
It is commonly afflicted by cancer.
A well-know mimicker of cancer is malakoplakia.[1]
Normal
Microscopic
- Muscularis mucosae - thin, discontinuous.
- Fat - many be in lamina propria.
Note:
- On TURBT - don't ever call T3.
Urinary bladder cancer
The most common type of cancer to affect the bladder is urothelial carcinoma, which is covered in the urothelium article.
Urachal carcinoma
General
- Rare.[2]
- Classically - dome of bladder lesion.
- Younger <55 years-old.
Microscopic
Patterns
- Enteric - looks like colonic adenocarcinoma.
- Mucinous.
- Signet ring.
DDx:
- Metastatic adenocarcinoma/adenocarcinoma extending from another structure.
- Adenocarcinoma arising from the urinary bladder.
