RT Journal Article SR Electronic T1 Haemophagocytic lymphohistiocytosis: an elusive syndrome JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 432 OP 436 DO 10.7861/clinmedicine.16-5-432 VO 16 IS 5 A1 William Thomas A1 Mars van’t Veer A1 Martin Besser YR 2016 UL http://www.rcpjournals.org/content/16/5/432.abstract AB Haemophagocytic lymphohistiocytosis is a rare inflammatory condition. It can present in adult general medical patients and is a challenging diagnostic conundrum. This article provides an overview of the pathophysiology and clinical presentation of the syndrome for the general physician who will be rarely confronted with this problem but will have to act promptly when the situation arises. Treatment is also briefly discussed, although this usually occurs in a specialist setting after the diagnosis has been established.
