Delusional parasitosis

Delusion of parasitosis is a hypochondrial psychosis usually monosymptomatic, where the patient is convinced of being infested with animal parasites while no objective evidence exists to support this belief. The complains are mostly of skin, and rarely of gastrointestinal infestation. Delusional parasitosis is very real and distressing to the patient, causing him to visit medical centers for advice from family practitioners, dermatologists, and parasitologists.

We reported a cluster of cases shared by 5 family members, triggered by a gift, which was brought by the daughter from her trip to Nepal, and which was believed to be infested with parasites (A 133).
