Abstract
Objective Delusional parasitosis (DP) is a difficult-to-treat condition. It is prevalent in all cultures, societies, and countries. Previous case reports of DP have been published; however, the patient presented in this report is unique because of the co-occurrence of both primary and secondary types of DP. We aim to explore the two subtypes of DP. Conclusions We discuss DP from a nosological perspective and also highlight the various theories at play in the pathogenesis of primary and secondary DP. The different subtypes of DP should be taken into consideration as they also have a bearing on the management.
Highlights
Delusional parasitosis (DP) is a false, firm, unshakable belief that one is infested with bugs, parasites, worms, mites, lice, insects, or similar creatures, held with delusional intensity [1]
It is known that dopamine transporter (DAT) inhibitors, like amphetamine derivatives, which block synaptic reuptake of dopamine, can induce the clinical expression of DP-like symptoms [4]
DP is a condition frequently seen by psychiatrists, dermatologists, and primary care physicians
