Exegesis. – We report three new cases of Kikuchi's disease: the first one mimicked a systemic lupus, the second one was associated with a lupus-like rash, and a the last one was a severe case with hemophagocytic syndrome and a primo-infection with Epstein-Barr virus revealing a systemic lupus erythematosus.
Conclusion. – Clinical and biological follow-up of patients presenting with Kikuchi's disease is necessary to look for an association with a lupus. We discuss the pathogenic links between Kikuchi's disease and lupus.
