Abstract:
Three identical case histories consisting of circular delimited petechial purpura around the mouth and chin in children aged 13-15 years are presented. This form of purpura was undoubtedly due to self-mutilation by establishing of a vacuum over the skin produced by a tumbler from which the air had been partially aspirated. This is regarded as a symptom of hysterical conversion on account of stressing conditions at home or in school. Strategies for making the patient and the parents aware of the causal connection and the possibilities for intervention are mentioned.
