Kikuchi's disease and systemic lupus erythematosus: case report and review

Abstract The case of a 50-year-old male with a clinical syndrome consistent with systemic lupus erythematosus (SLE), generalized lymphadenopathy, and renal involvement is presented. The pathologic examination of an excised supraclavicular lymph node showed necrotizing lymphadenitis. Although necrotizing lymphadenitis is a well-known characteristic of SLE lymphadenitis, the main histologic and immunophenotypic findings of our case showed the presence of distinctive Kikuchi's lymphadenitis.
