<unk>  was first described by Klob in 1859. It is a very rare condition in which small groups of pancreatic cells are separate from the pancreas. They may occur in the mesentery of the small intestine, the wall of the duodenum, the upper part of the jejunum, or more rarely, in the wall of the stomach, ileum, gallbladder or spleen. The cause is not very clear. It is thought to be related to abnormal embryo development. Some patients with<unk>  may not show any symptom or sign. Some patients are revealed by other diseases or examination. Usual symptoms and signs include low-grade fever, weakness and fatigue, pain in the upper abdomen or epigastric area, itching, nausea and vomiting, or jaundice. Ther is no specific test for<unk> . Laboratory analyses of blood, urine, stool, and pancreatic fluid, and abdominal imaging studies may help diagnose. Surgical of removal of<unk>  is the main treatment. The prognosis of<unk>  depends on whether secondary pathologic changes take place or not. If any carcinomatous change on<unk> , outcome of patient is poor.
