Abstract
Background
Hemophagocytic lymphohistiocytosis (HLH) is a severe clinical entity associated with high mortality in the adult population. HLH has been associated with infections, malignancy and autoimmune conditions such as Systemic Lupus Erythematosus (SLE), however this is often in the context of a disease flare. Currently, there are limited reports of inaugural SLE manifesting as HLH with a lack of consensus on treatment and management of these patients.
Case presentation
Here, we present two rare case reports of severe cutaneous manifestation of lupus associated with HLH. Both patients presented with sinister clinical courses with primarily rheumatologic complaints including malaise, arthralgia, and myalgia with biochemical abnormalities. Both patients were diagnosed with HLH as a result of first presentation from cutaneous lupus. A comprehensive literature review using the PubMed database with cases comprising keywords of HLH and SLE up to September 2017 was conducted, with an emphasis on inaugural cutaneous SLE cases.
Conclusions
Ultimately, we highlight that a keen clinical acumen is required as misdiagnosis may lead to insufficient treatment with adverse clinical outcomes with the unique presentation of HLH from inaugural cases of SLE.
