Scabies-associated angioimmunoblastic lymphadenopathy.

A systemic disorder characterized by fever and reactive lymphadenopathy developed in a patient with scabies infestation. Regression of all clinical symptoms and signs occurred after antiscabies therapy. Two months later, the whole clinical picture reappeared concomitantly with scabies reinfestation. Subsequent lymph node biopsy demonstrated typical angioimmunoblastic lymphadenopathy (AILD). It is plausible that persistent antigenic stimulation caused by scabies infection was of pathogenetic importance in the induction of the syndrome of AILD. Infectious agents should be considered and looked for in patients with AILD, since they may play a role in the evolution of this disease.
