Delusions of parasitosis.

Patients with delusions of parasitosis (DOP) are more commonly recognized in dermatology practices today. However, dermatologists may feel uncomfortable treating these patients because of the psychiatric nature of their disorder. As a result of the fact that DOP patients strongly prefer to seek treatment from dermatologists rather than mental health professionals, it is important for dermatologists to be well equipped with a basic understanding of the disorder and with tools to assist this patient population. In this review, we discuss the epidemiology, presentation, differential diagnosis and treatment strategy for patients with DOP.
