Necrotizing lymphadenitis: Kikuchi--Fujimoto disease alias lupus lymphadenitis?
Differentiation between lymphadenopathy in potentially life-threatening systemic lupus erythematosus (SLE) and self-limiting necrotizing lymphadenitis, also called Kikuchi- Fujimoto disease (KFD), is difficult. In the past, co-occurrence of SLE and KFD has been described repeatedly in case reports. Here, we report a case of necrotizing lymphadenitis, describe the clinical and histopathologic features in detail and discuss the current literature. KFD may in fact be a histopathologic characteristic of SLE supporting the hypothesis that KFD is a rare manifestation of SLE. To clarify whether KFD is the same entity as lupus lymphadenitis, more cases with SLE and lymphadenopathy should be examined in detail.
