Gardner-Diamond's syndrome, or autoerythrocyte sensitization, is a disorder of spontaneous, painful ecchymoses whose pathogenesis is unresolved. The role of psychopathologic factors in this entity has been emphasized in previous reports. The patient in this study had a classical history and characteristic clinical features and is, to my knowledge, the first man described with this disorder.
