The New England Journal of Medicine has published a clinical image case of Type 1 autoimmune pancreatitis, a rare condition that can be mistaken for pancreatic cancer.
The New England Journal of Medicine (@NEJM) posted the case to its social media channels, flagging it under its Images in Clinical Medicine series — a long-running feature that uses real patient scans and clinical photographs to illustrate conditions that doctors may rarely encounter. Type 1 autoimmune pancreatitis (a condition where the body’s immune system attacks the pancreas, causing inflammation) is one such condition: uncommon enough that it can go unrecognised, yet serious enough that the distinction between it and pancreatic cancer matters enormously for treatment.
Unlike pancreatic cancer, Type 1 autoimmune pancreatitis typically responds well to steroid treatment. But because the two conditions can look similar on scans and share symptoms — including jaundice (yellowing of the skin and eyes), abdominal pain, and weight loss — getting the diagnosis right is essential.
The condition belongs to a group called IgG4-related disease, where raised levels of a particular antibody (IgG4) drive inflammation in organs including the pancreas. According to the NHS, autoimmune pancreatitis is rare, and most people who develop it are middle-aged or older men.
If you’re experiencing persistent abdominal pain, unexplained weight loss, or yellowing of the skin, speak to your GP rather than waiting to see if symptoms ease.
