Systemic lupus erythematosus with simultaneous onset of Kikuchi-Fujimoto's disease complicated with antiphospholipid antibody syndrome: a case report and review of the literature

Abstract

Histiocytic necrotizing lymphadenitis, called Kikuchi-Fujimoto's disease (KFD), is an idiopathic, self-limited condition rarely associated with systemic lupus erythematosus (SLE). The cause of concomitant KFD and SLE is still unknown. We describe a 19-year-old man simultaneously diagnosed with both KFD and SLE complicated with deep vein thrombosis (DVT). To the best of our knowledge, this is the first case report of KFD associated with SLE complicated with antiphospholipid antibody syndrome (APS). Our patient was successfully treated with intravenous pulse methylprednisolone, anticoagulation with heparin, oral hydroxychloroquine, azathioprine, and low-dose aspirin.
