The skin is the largest organ of the body covering a surface area of 1.5 to 2 square metres in the average adult. It plays a vital role in the interface with external elements and because of its visibility has tremendous social significance. The skin and the nervous system share a common embryonic origin from the ectoderm and hence pathology in one organ system is likely to affect the other.

The purpose of this module is to alert the clinician to potentially treatable psychiatric disorders that may underlie some dermatological disorders and to review the salient clinical features and psychiatric treatments that have been reported to be effective.
