Histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis) in an HIV-positive patient Linfadenite necrosante histiocítica (linfadenite de Kikuchi) em um paciente HIV-positivo

Histiocytic necrotizing lymphadenitis, or Kikuchi's lymphadenitis (KL), is an unusual form of lymphadenitis, generally with self-limited clinical course. KL has been reported in rare patients infected with the human immunodeficiency virus (HIV). Pathogenesis of the lesion is probably related to...
