Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis): report of a case with other autoimmune manifestations.
Kikuchi-Fujimoto disease (KFD), or histiocytic necrotizing lymphadenitis, is a benign and self-limited disease that mainly affects young women. Patients present with localized lymphadenopathy, fever, and leukopenia in up to half of the cases. KFD can occur in association with systemic lupus erythematosus. We present the case of a patient with KFD and systemic lupus erythematosus, as well as relapsing polychondritis. This patient had persistently low C4 complement levels, so she was evaluated for a genetic defect in complement production and was found to have two "null" C4 alleles. We believe that this may have contributed to the development of her diseases.
