Delusions of parasitosis

Area of Science:

• Dermatology
• Psychiatry

Background:

• Delusions of parasitosis (DP) is a common monosymptomatic hypochondriacal psychosis seen in dermatology.
• Patients experience a fixed, false belief of being infested with parasites or having foreign bodies emerging from the skin, often with tactile hallucinations.

Purpose of the Study:

• To highlight the importance of recognizing and managing delusions of parasitosis in dermatological practice.
• To emphasize the role of therapeutic alliance and pharmacotherapy in successful patient outcomes.

Main Methods:

• Review of clinical presentation and management strategies for delusions of parasitosis.
• Discussion of treatment approaches including antipsychotic medications.

Main Results:

• Patients often present with a long history of symptoms and multiple physician visits across specialties.
• Antipsychotic medications such as pimozide and risperidone demonstrate high response rates in patients with DP.
• Developing a therapeutic alliance is crucial for positive clinical interactions.

Conclusions:

• Dermatologists must be equipped to manage delusions of parasitosis effectively.
• A patient-centered approach focusing on therapeutic alliance and appropriate pharmacotherapy is key to successful management.
