A case of aseptic abscesses syndrome treated with corticosteroids and TNF-alpha blockade

Abstract

Aseptic abscesses syndrome (AA) is an emerging clinicopathological entity characterized by visceral sterile collections of mature neutrophils that do not respond to antibiotics but regress quickly when treated with corticosteroids. Although most previous case reports of AA have been restricted to Europe, we present here a Japanese woman with AA showing recurrence of splenic abscesses, ileocolitis, pyoderma gangrenosum, and arthritis. Although both steroid therapy and tumor necrosis factor (TNF)-alpha blockade were effective, relapses remained frequent.
