Morgellons disease is a skin condition marked by lesions [often] containing unusual fibers or filaments that emerge from or are embedded within the skin.
Morgellons disease is generally regarded as a delusional disorder with fibers attributed to textile contamination introduced by compulsive scratching.
However, a growing number of researchers propose that these fibers are produced by human cells in response to infection. This review traces
the evolution of Morgellons fiber research, from early skepticism – due to misidentification and superficial collection of fibers – to evidence supporting their biological origin.
We also present previously unpublished data and observations demonstrating the cellular origin of these fibers. Rigorous chemical, molecular, microscopic,
and spectroscopic analyses confirm that Morgellons fibers are primarily composed of keratin and collagen, produced by keratinocytes and fibroblasts,
and sometimes manifest as small human hairs.
Unique properties include autofluorescence under ultraviolet light and abnormal eumelanin and pheomelanin pigmentation.
Recent studies have detected pathogenic bacterial antigens and amyloid components within the fibers, suggesting a complex interplay between infection
and filament formation.
Accumulating evidence underscores the need for rigorous methodology and open-minded inquiry to examine the human cellular nature of Morgellons fibers and to address unresolved questions about pigmentation, autofluorescence and microbial involvement.
