Pancreatic Cancer: Although less common, pancreatic cancer can present with abdominal pain and itching due to the obstruction of bile ducts or the release of substances that cause itching.

Primary Biliary Cholangitis (PBC): A chronic liver disease characterized by the progressive destruction of the bile ducts within the liver, leading to itching and abdominal pain.
