Description
Hind Qajia and colleagues present a case where pancreatic cancer hid behind the signs of autoimmune pancreatitis in a 2026 report. Their patient, aged fifty-one, arrived with progressive jaundice and unintentional weight loss. Blood work showed blocked bile flow, raised tumor markers, and a markedly elevated IgG4 level, the antibody signature of autoimmune pancreatitis.
Imaging deepened the ambiguity: the pancreas was diffusely swollen into the sausage shape typical of the autoimmune disease, and the main duct was irregularly narrowed without the upstream widening cancer usually causes. Yet the same scan showed a focal lesion in the uncinate process, enlarged regional lymph nodes, and nodules with fluid in the abdomen. Biopsy settled the question in favor of pancreatic ductal adenocarcinoma growing within the suspected autoimmune picture. The authors warn that a reassuring IgG4 result and classic autoimmune imaging must never close the case.
