Autosensitization to DNA: evidence for an immunologic basis

Psychogenic Purpura (Gardner-Diamond Syndrome)

Psychogenic purpura, also known as Gardner-Diamond syndrome or autoerythrocyte sensitization syndrome, is a rare condition characterized by spontaneous development of painful edematous skin lesions progressing to ecchymosis over the next 24 hours. Severe stress and emotional trauma always precede the skin lesions. The condition is most commonly seen in women, but isolated cases have been reported in adolescents and in males. Psychodermatologic evaluation and dermatology and psychiatry liaison have been successful in the treatment of these patients. This report provides an overview of psychogenic purpura and presents the case of a 15-year-old girl.
