Morgellons

Morgellons is a disputed condition characterized by reports of fibers or other materials emerging from the skin, often with itching and skin lesions. Its cause and status as a distinct disease remain contested.

Morgellons disease investigation: A 2012 CDC study examining skin samples and health reports from people who described Morgellons symptoms. It found that sampled fibers were mostly cellulose and did not establish a distinct infectious cause.
Dermatologic examination: The clinical assessment of skin, hair, and nails for signs of disease or injury. Direct examination and sample analysis help distinguish skin disease from fibers introduced from clothing or surroundings.
Centers for Disease Control and Prevention: A United States public health agency that investigates disease and issues health guidance. Its investigation found no common underlying medical condition among the studied participants.
Medically unexplained symptoms: Physical symptoms for which available medical evaluation has not identified a sufficient explanation. Morgellons reports raise questions about how medicine should classify symptoms without an established cause.
Cutaneous larva migrans: A parasitic skin condition in which migrating larvae produce raised, winding tracks. It is a confirmed cause of visible skin changes, unlike the unverified organisms sometimes suspected in Morgellons.
Skin biopsy: A procedure that removes a small skin sample for microscopic or laboratory examination. Biopsies can test for inflammation, infection, or other tissue changes in reported lesions.
Charles E. Holman Foundation: A nonprofit organization that advocates research and support for people reporting Morgellons. Its advocacy reflects the view that Morgellons warrants recognition and dedicated investigation.
Patient-reported outcome: A health outcome reported directly by a patient without interpretation by a clinician. Systematic symptom reports can preserve patients’ experiences even when objective findings remain inconclusive.
Delusional infestation: A psychiatric condition involving a fixed belief of infestation despite lack of supporting evidence. Some medical accounts interpret Morgellons reports through this diagnosis, a framing disputed by affected people.
Cellulose: A structural carbohydrate that forms plant cell walls and occurs in cotton and other fibers. Cellulose was identified in many fibers examined in the CDC investigation.
