Which is NOT a common symptom of primary biliary cholangitis (PBC)?

Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease characterized by the gradual destruction of the bile ducts within the liver. The main symptoms commonly associated with PBC include fatigue, jaundice, and splenomegaly.

Fatigue is often one of the earliest and most prominent symptoms reported by patients, greatly impacting their quality of life. Jaundice occurs as the disease progresses and liver function declines, leading to elevated bilirubin levels in the blood. Splenomegaly, or an enlargement of the spleen, can also occur due to portal hypertension associated with liver damage.

While a skin rash can occur in various liver diseases, it is not typically recognized as a common symptom of PBC. Instead, PBC is more characteristically linked to the aforementioned symptoms of fatigue, jaundice, and splenomegaly, making the skin rash an uncommon manifestation and thus the correct choice for the question. Understanding these typical symptoms can aid in early recognition and management of PBC.
