Gallbladder carcinoma is a malignant epithelial neoplasm arising from the gallbladder. Most gallbladder carcinomas are adenocarcinomas.
General
- Uncommon.
Treatment:
- Cholecystectomy +/- lymph nodes +/- partial hepatectomy.[1]
Epidemiology
- Associated with gallstones.
- Increased risk in primary sclerosing cholangitis.
- Sex: female > male.
- Location: usually fundus, sometimes body.
Notes:
- Diffuse calcification of gallbladder wall, AKA "porcelain gallbladder" is not associated with carcinoma - based on a series of 10,741 cholecystectomies.[2]
- Focal mucosal calcification is associated with malignancy.[3]
- Cholangiocarcinoma is dealt with in the liver neoplasms article.
Gross
- Classic: mass projecting into the lumen.
- Marked gallbladder wall thickening.
- >10 mm should be considered with suspicion.[4]
Image:
Microscopic
Features:
- Usually adenocarcinoma.
- Mimics appearance of pancreatic ductal adenocarcinoma -- but less cellular mucin.[5]
Notes:
- May be very subtle, i.e. difficult to differentiate from normal glands.
- "Deep glands" that look bland shouldn't immediately be dismissed as benign.
Subtypes:
DDx:
- Adenomyoma of the gallbladder.
- Gallbladder adenoma.
- Metastatic carcinoma.
- Chronic cholecystitis with glands extending deep into the wall.

At right lie acini and nests of round and sometimes spindled cancerous nuclei. Overall most of the tumor was in tubules/acini, meaning the lesion is moderately differentiated. C.
