Pancreatic cancer may manifest through specific skin symptoms

Pancreatic cancer often progresses with minimal early digestive symptoms, but certain dermatological signs may appear before traditional indicators like abdominal pain or weight loss.

One of the most documented signs is jaundice (icterus), which occurs when a tumor at the head of the pancreas compresses the bile duct, causing bilirubin to build up in the blood. This can manifest as yellowing of the skin and eyes, dark urine, and pale stools. This condition is often accompanied by cholestatic pruritus, or intense, widespread itching.

Other potential skin indicators include: - Pancreatic panniculitis, linked to the release of enzymes like lipase and amylase into the bloodstream. - Migratory necrolytic erythema, a rash associated with glucagonomas (endocrine tumors). - Sister Mary Joseph nodules, which are skin nodules appearing near the navel due to metastases.

Medical authorities, including the NHS, emphasize that the appearance of jaundice in adults requires rapid medical evaluation.
