Disease & Conditions Delusions of parasitosis occur in disturbed or anxious eccentric individuals. This disorder begins as intractable pruritus with a crawling sensation in the skin. The patients are convinced that they are harboring parasites and usually bring “specimens” to prove infestation. These bits of material or skin must be examined to rule out a true infestation and to assure the patient of your interest in the problem.

LSC is also associated with atopy, or atopic dermatitis (eczema).
