Delusional Parasitosis

1. Suffered from infestation for long

2. Seen by numerous physicians,

exterminators, parsitologists,

hygienists and entomologists

3. Consistently and fiercely reject

negative findings or any that

deviate from their perceptions

4. “Matchbox sign"

– Containers of dust, lint, skin

scrapings, toilet paper, dried blood

or scabs, hair or other pieces of

human tissue

5. Self mutilation ranging from

scratches to deep ulceration

– From attempting to dig out bugs

6. One or more family members

may share delusion

– Folie à deux / Folie à trois

7. Use of home remedies, distrust

of prescription drugs

8. Self exposure to often

dangerous levels of pesticides

• Similar to “cocaine bugs”

– Patient feels parasites crawling

under his skin

• Also associated with high fever,

extreme alcohol withdrawal

– Often associated with visual

hallucinations of insects

Morgellon’s Syndrome

1. “Filaments” in and on skin

2. Movement sensations, both

beneath and on skin

3. Skin lesions: spontaneously

appearing and self-generated

4. Musculoskeletal pain and

headaches

5. Aerobic limitation: universal and

significant

6. Cognitive dysfunction: short-

term memory and attention

deficit

7. Emotional effects: loss of

boundary control
