A study of skin disorders in patients with primary psychiatric conditions.
BACKGROUND
The skin occupies a powerful position as an organ of communication and plays an important role in socialization throughout life. The interface between dermatology and psychiatry is complex and of clinical importance.


OBJECTIVE
To document the incidence of cutaneous disorders in patients with primary psychiatric conditions.


METHODS
Three hundred patients with a primary psychiatric condition who had cutaneous disease were entered into the study group. The patients were classified appropriately based on the classification of psychocutaneous disorders. The control group included 300 patients presenting with a skin disorder and without any known psychiatric complaint.


RESULTS
The majority of the cases in the study group were in the 3rd-5th decade. In this study, the most common primary psychiatric conditions were manic depressive psychosis (53.33%), depression (36.33%), schizophrenia (8.33%) and anxiety (2%). Of the study group, 68.66% patients had infective dermatoses and the rest had non-infective dermatoses. A high incidence of pityriasis versicolor and dermatophyte infections was noted in males from the study group. Among non-infective dermatoses, 8% had eczema, and psychogenic skin disorders were seen in 4.67% of the study group. Of these, delusions of parasitosis were the commonest (2%) followed by venereophobia (1%).


CONCLUSIONS
A statistically significant higher incidence of tinea versicolor and dermatophyte infections was seen in the study group. Delusion of parasitosis was the most common psychogenic skin disorder seen in the study group, followed by venereophobia.
