Granulomatous pancreatitis is a rare disorder and recognized rarely during life or non-operatively. Noncaseating granulomas in the pancreas, histologically indistinguishable from sarcoidosis, can be seen in a variety of diseases such as tuberculosis, fungal infection, berylliosis, Hodgkin's disease, non-Hodgkin's lymphoma and Crohn's disease. Therefore, as with other granulomatous diseases, a tissue biopsy is essential for the diagnosis. Its clinical presentation is often similar to pancreatic cancer, with common presenting symptoms including abdominal pain, weight loss, jaundice, and anorexia. We report a case of idiopathic granulomatous pancreatitis in a 56-year-old women whose clinical and radiographic findings were suggestive of pancreatic cancer.
