title: Spontaneous rupture of a pancreatic acinar cell carcinoma presenting as an acute abdomen.
abstract: BACKGROUND
  Pancreatic acinar cell carcinoma is a rare malignant pancreatic neoplasm. To the best of our knowledge, there has been no report on spontaneous rupture of acinar cell carcinoma.
  
  
  METHODS
  A 39-year-old Azari male presented with a history of sudden onset, acute epigastric pain of 12-h duration. Eight hours later the patient's general condition rapidly deteriorated, blood pressure was decreased to 90/70mm/Hg and heart rate was increased to 120beat/min. Emergent abdominal computed tomography scan showed a well-defined hypo-dense, necrotic mass, measured 12cm×12cm that was originating from the uncinate process of pancreas with marked free peritoneal fluid and extensive haziness of retroperitoneal and mesenteric fat compatible with marked bleeding. Emergent abdominal operation was performed and histopathology revealed acinar cell carcinoma of the pancreas.
  
  
  CONCLUSIONS
  Pancreatic acinar cell carcinoma (ACC) usually presents with abdominal pain, nausea and vomiting. To best of our knowledge, no report has been made of spontaneous rupture of ACC.
  
  
  CONCLUSIONS
  Pancreatic carcinoma may present as acute abdomen due to rupture of underlying neoplasm.
