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,
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).
