Case Discussion

Gallbladder cancer is a rare disease that often arises in the setting of chronic inflammation.

In the vast majority of patients the source of this chronic inflammation is cholesterol gallstones.

Other more unusual causes of chronic inflammation are primary sclerosing cholangitis, ulcerative colitis, liver flukes, chronic Salmonella typhi and paratyphi infections.
