Autoerythrocyte sensitization.
We have seen six examples of autoerythrocyte sensitization in children that allow a definition of the disorder in the pediatric age group. The typical skin lesion is a painful, erythematous bruise that starts after minor trauma or surgery and often involves an area away from the injury site. The skin manifestations can be debilitating, and reappear unpredictably for an indefinite period. Somatic symptoms can be associated with the bruising. Usually the children have a disturbed psychological background. Characteristically, multiple detailed investigations are performed before the diagnosis is made. An intradermal injection of autologous red cells may or may not give a "positive" ecchymotic reaction. Pediatric patients seem to respond well to psychotherapy, which is usually the only effective form of treatment.
