Refractory Delusional Parasitosis in a 70-year-old Woman.

This is a case report of delusional parasitosis in a 70-year-old woman. Delusional parasitosis, or delusional infestation, is a rare disorder typified by the false belief that an individual is infected with insects or parasites. Management focuses on developing a strong, caring relationship with the patient. It is widely debated whether health care providers should agree or disagree with the patient's delusions. Due to the rarity of this disorder, our hope in presenting this incidence is to motivate more research for treatment.
