Hemophagocytic lymphohistiocytosis accompanying Still's disease: A case report

Abstract

Key Clinical Message Hemophagocytic lymphohistiocytosis (HLH) is a rare hematologic disease that occurs due to immune system dysfunction. Clinical manifestations of this disease are fever, increased ferritin level, cytopenia, and hemophagocytosis in the biopsy report of the bone marrow. We report a 36‐year‐old woman referred to our hospital with persistent fever, arthralgia in interphalangeal joints, and cutaneous rash on the trunk, was subsequently diagnosed as an adult‐onset Still's disease (AOSD), and after bone marrow aspiration, HLH was diagnosed with her.
