A Myeloid Sarcoma Presenting as Acute Pancreatitis in a Previously Healthy Patient without Any Visible Pancreatic Mass on Computed Tomography

We describe a previously healthy girl presented with acute pancreatitis without any evidence of gallstones or mass formation on computed tomography or transabdominal ultrasonography. Myeloid sarcoma finally diagnosed based on immunophenotyping of pancreas tissue, ascites and pleural fluid by flow cytometry. Bone marrow aspirate cytometry was unremarkable.
