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.
