Still's disease associated with necrotizing lymphadenitis (Kikuchi's disease): report of 3 cases

Necrotizing lymphadenitis (Kikuchi's disease) is recognized as one of the benign lymphadenopathies. Previously, this condition has not been described in Still's disease which is frequently associated with lymphadenopathy. We report 3 cases of Still's disease, 2 in adults and 1 in an older child, with the findings of necrotizing lymphadenitis on lymph node biopsy. Considering the common infectious and/or immunologic etiologies described in both disorders, coexistence of both conditions suggests the possibility that they share a common etiology.
