[Recurrent lymphadenitis was Kikuchi-Fujimoto disease]. / Lymfadenit som mystiskt återkom var Kikuchi­Fujimotos sjukdom.

Kikuchi-Fujimoto disease, or histiocytic necrotizing lymphadenitis, is in most cases a benign disease which affects lymph nodes in the cervical region. Cervical adenopathy and fever are the most common symptoms, and young adults are mostly affected. Lymph node biopsy is the mode of diagnosis with demonstration of paracortical areas of apoptotic necrosis with abundant karyorrhectic debris and a proliferation of histiocytes, plasmacytoid dendritic cells, and CD8+ T cells in the absence of neutrophils. In most cases, the disease is self-limiting but it can be recurrent or evolve to SLE. Treatment varies from symptomatic to more systemic with cortisone and intravenous immunoglobulin.
