Morgellons (also called Morgellons disease or Morgellons syndrome) is a name that was given in 2002 by stay-at-home-mom 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). Most doctors, including dermatologists[3] and psychiatrists,[4] regard Morgellons as a manifestation of known medical conditions, including delusional parasitosis.
