Psychodermatology-A review of the relationship between dermatology and psychiatry

Abstract

Background:

The prevalence of psychiatric illness among patients attending dermatology clinics is high. Three major categories of disorder exist; Psychosomatic disorders, Primary psychiatric disorders and Secondary psychiatric disorders.

Aim:

To investigate the relationship between Dermatological conditions, in particular Dermatitis Artefacta and Psychiatric disorders and to discuss course and management of these disorders.

Method:

All referrals from Dermatology clinics in South Dublin to the Psychiatry service over a six- month period were reviewed. Psychiatric Diagnosis was noted, the prevalence of each of these and their management.

Results:

90% of referrals had a psychiatric diagnosis. I focused on one particular case of a 22 year old woman referred by her dermatologist, presenting with bizarre, well-demarcated, linear lesions that appeared to develop "overnight". In joint consultation with the dermatology team, a diagnosis of Dermatitis Artefacta was made. In this review I discuss the features, associated psychopathology, epidemiology, aetiology and management of this rare condition.

Conclusion:

Psychiatric illness should be considered in all patients attending dermatology clinics. If a psychiatric disorder is diagnosed, close collaboration between dermatologists and psychiatrists is essential if a favourable outcome is to be achieved.
