Still's Disease Relapse with Severe Pneumonitis After Prolonged Remission

Abstract

A 20-year-old woman who had suffered from Still's disease was admitted for fever and progressive pneumonitis after long-term remission. High spiking fever, leukocytosis, splenomegaly and an extremely high serum ferritin concentration strongly suggested a relapse of Still's disease. Intensive therapy with high-dose methylprednisolone, cyclophosphamide and gammaglobulin was required for the severe pneumonitis, which was thought to be a rare manifestation in Still's disease. © 1993, The Japanese Society of Internal Medicine.
