Hemophagocytic Lymphohistiocytosis Syndrome: A Rare Manifestation of Acute Pancreatitis.

Hemophagocytic lymphohistiocytosis syndrome (HLH) is a rare hyperinflammatory disorder linked to acute pancreatitis. While there are only a few case reports available on this particular association, we would like to share the case of a 60-year-old man who experienced acute-onset abdominal pain typical of pancreatitis. Three days after admission, he developed fever, pancytopenia, hypertriglyceridemia, and hyperferritinemia. A bone marrow biopsy performed for evaluation of fever revealed hemophagocytosis. Initiation of treatment for HLH showed dramatic improvement. It is important to note that while HLH may be rarely associated with pancreatitis, early diagnosis and treatment is critical and can be life-saving.
