Morgellons

Morgellons (also called Morgellons disease or Morgellons syndrome) is a name that was given in 2002 by Mary Leitao to a proposed condition characterized by a range of cutaneous (skin) symptoms including crawling, biting, and stinging sensations (formication); finding fibers on or under the skin; and persistent skin lesions (e.g., rashes or sores). Doctors, including dermatologists and psychiatrists, regard Morgellons as a form of delusional infestation (also called delusional parasitosis), i.e. the belief that there is a pathogenic infestation despite contrary medical evidence.
