Morgellons disease is an infrequent syndromic condition, that typically affects 
middle-aged white women, characterized by crawling sensations on and under the 
skin, associated with itchy rashes, stinging sores, fiber-like filaments 
emerging from the sores, severe fatigue, concentrating difficulty, and memory 
loss. The scientific community is prone to believe that Morgellons is the 
manifestation of various psychiatric syndromes (Munchausen, Munchausen by proxy, 
Ekbom, Wittmaack-Ekbom). Up until now, no investigative science-based evidence 
about its psychogenesis has ever been provided. In order to close this gap, we 
have analyzed the filaments extracted from the skin lesions of a 49-year-old 
Caucasian female patient, by using a Field Emission Gun-Environmental Electron 
Scanning Microscope equipped with an X-ray microprobe, for the chemico-elemental 
characterization of the filaments, comparing them with those collected during a 
detailed indoor investigation, with careful air monitoring, in her apartment. 
Our results prove the self-introduction under the epidermis of environmental 
filaments. For the first time in the literature, we have scientifically 
demonstrated the self-induced nature of Morgellons disease, thereby wiping out 
fanciful theories about its etiopathogenesis.
