Isolated granulocytic sarcoma of the pancreas: A tricky diagnostic for primary pancreatic extramedullary acute myeloid leukemia

We report two clinical cases of primary granulocytic sarcoma of the pancreas that were diagnosed on the surgical specimen. Atypical clinical and morphological presentations may have lead to pretherapeutic biopsies of the pancreatic mass in order to indicate primary chemotherapy. Literature review of this rare clinical presentation may help physicians to anticipate diagnostic and therapeutic strategies.
