Extract

Patients seen with complaints of fibers extruding from the skin associated with nonspecific dermatologic and neuropsychiatric symptoms have been diagnosed as having Morgellons disease. The cause of Morgellons disease and its relationship to delusional infestation (DI) remain controversial. A heterogeneous diagnosis, DI is the most common delusional disorder in dermatology and shares features with Morgellons disease.1
