Black ascitic fluid in a patient with history of alcohol abuse: report of an unusual case and literature review

The differential diagnosis for black ascites include pancreatic ascites (PA). In majority of cases described the ascitic fluid as amber or black-colored. We report the case of a 33-year-old man with a history of alcohol abuse who presented with 24 h of epigastric pain and abdominal distension. Laboratory results showed lipase of 1270 U/l, amylase of 442 U/l and albumin of 2 g/dl. A contrast computed tomography scan of the abdomen showed pancreatic necrosis with atrophy and free abdominal fluid. Paracentesis was performed, yielding opaque black ascitic fluid. An ascitic fluid analysis demonstrated amylase of 2769 U/l, albumin of 1.6 g/dl, was negative for malignant cells and tuberculosis. Serum-Ascites Albumin Gradient was resulted in 0.4. The diagnosis of chronic pancreatitis was suspected, and he received supportive care with pain medication and bowel rest. He was discharged with symptom free on Day 14 after admission.
