Introduction: Morgellons disease is a rare, unexplained skin disorder that whose specific etiology remains a mystery to both the Dermatologic and Psychiatric community as the specific etiology remains unknown. The condition is characterized by the physical resentation of painful sores with reported crawling sensations within the skin and the fixed belief of infection or parasitic infestation. The
pathognomonic feature of this disease is the presence of filaments or fibers embedded in and emerging from these sores.
Objectives: A systematic review was conducted to include 174 patient cases of Morgellons disease to evaluate for clinical presentation, psychiatric status, and effective treatment methods.
Data synthesis: Most patients were middle-age women from the United States presenting with $1 patch or erosion located anywhere on the body. Most cases reported associated symptoms of pain, itching, bleeding, fiber presentation within the lesion, formication, extreme fatigue, weakness and impaired memory and attention. Analysis of all cases revealed no common fiber etiology, suggesting environmental exposure rather than infectious etiology. Overall, histopathologic examination of lesions did not demonstrate the presence of parasitic/microbial/-
fungal infection or infestation of any sort. Medical history of psychiatric illness was present in a significant number of cases, indicating that Morgellons disease is associated with mental illness and should be classified as a subset of delusional parasitosis. Ultimately it was concluded that there was no common underlying medical condition or infectious organism in Morgellons cases.
Conclusion: The most effective treatment for Morgellons disease employs pharmacologic antipsychotic therapy combined with thorough psychiatric evaluation and monitoring by a clinical psychiatrist in close collaboration with a dermatologist. Pharmacologic drugs of choice include second generation, atypical antipsychotics such as risperidone, amisulpride, and olanzapine. This present article represents the most comprehensive review of a very rare disorder and recommends labeling Morgellons disease as a disorder of delusional infestation to more effectively recognize early clinical presentation and treatment options for this psychiatric illness.
