Isolated Pancreatic Extramedullary Hematopoiesis

Abstract
A 59-year-old man with lung cancer, peripheral blood leukocytosis and thrombocytosis without peripheral lymphadenopathy and hepatosplenomegaly was found to have pancreatic extramedullary hematopoiesis (EMH) in association with an ‘atypical’ myeloproliferative disorder. Studies for the Philadelphia chromosome and bcr-abl fusion product were negative. This is the first documented case in the literature of isolated EMH in the pancreas.
