Patients with delusional infestations (DI), previously named delusions of parasitosis, have a fixed, false belief that they are infested with living or non-living pathogens. Patients have abnormal cutaneous symptoms such as itching, biting, or crawling sensations. They often demonstrate self-destructive behavior in an effort to rid the pathogens from under their skin, leading to excoriations, ulcerations, and serious secondary infections. This review article aims to provide an overview of DI including its clinical presentation, diagnosis, and treatment. Strategies on how to establish a strong therapeutic alliance with DI patients are discussed. In addition, antipsychotic medications used in the treatment of DI are described.

Physicians are not infrequently consulted by distraught patients with delusions of infestation who believe that they are infested with external or internal parasites and describe a crawling sensation of bugs or worms on or under their skin. Internet search engines were queried with the keywords as search terms to examine the latest articles on delusional infestations in order to describe presenting manifestations, differential diagnoses, and effective management strategies. The demographic and behavioral features of delusional infestations have remained constant and include: (1) onset in well-educated, middle-aged adults who are pet owners; (2) production of purported specimens of causative parasites; (3) pesticide overtreatment of themselves, their households, and pets; (4) excessive cleaning or vacuuming of households; (5) intense anger and resentment directed at physicians failing to confirm their self-diagnoses; and (6) sharing delusional symptoms with spouses or relatives.
