AbstractMorgellons disease is a new emerging disease that is still controversial and believed to be, by some
practitioners, as nothing more than delusional parasitosis. The Center for Disease Control has recently launched an
epidemiological investigation into this disease due to the increased number of reports. A first case is reported of
an oral lesion and symptoms consistent with Morgellons disease. The nature of the characteristic fibers associated
with the intraoral lesion is investigated. Research has started at a number of institutions to elucidate the nature
of this emerging disease.

INTRODUCTION
In the 1600s, a disease reported by Sir Thomas Browne described that hairs on the back of children was called the
Morgellons, and this term has been coined to describe a recent emerging disease/syndrome with similar skin lesions.
From these lesions emerge hairs or fibers, which are associated with excoriation by the patient and a complaint of
itching or parasites crawling under the skin.1,2 Up until recently, this syndrome has been diagnosed as delusional
parasitosis by dermatologists, when confronted with the bizarre lesions and symptoms patients presented with and it
was treated as such.3-7 Delusional parasitosis is a term used by psychologists to describe a false belief by
patients that parasites or “bugs” are crawling under their skin where in reality, there are no parasites present.
Individuals with Morgellons disease report disturbing sensations of itching, worms or bugs crawling, and biting
under the skin, as well as nonhealing wounds in the skin from which emerge hairs or fiber-like materials or black
specks or crystal-like materials. Patients also suffer chronic fatigue and symptoms of depression, obsessive-
compulsive disorder, and attention deficit disorder (Morgellons Foundation 2007).8,9 Up to 94% of patients
suffering from this “Morgellons syndrome” also test positive for Lyme disease by Western blot.4,9 Research has
started at a number of institutions to elucidate the nature of this disease.10 A letter has been issued by
researchers at Oklahoma State University informing practitioners of the symptoms associated with this emerging
disease and caution them that the disease may not be purely a psychological problem.10
These symptoms are listed below:
Distinct and poorly healing skin lesions with unusually thick membranous scarring upon eventual healing.
Moderate to extreme pruritus at sites of lesions and unerupted skin lesions.
Microscopic examination of these lesions will most often reveal the presence of unusual fibers, which may be black
-blue or red. These fibers, which many health care providers initially thought to be textile contaminants, are
often present in the deep tissue of biopsies obtained from unbroken skin of individuals.
Careful examination of these fibers further reveals that they are frequently associated with hair follicles and are
definitely not textile in origin.
Most of these patients suffer from a host of neurological symptoms, which can vary in severity from mild to severe.
These neurological symptoms include tingling, paresthesias, and varying degrees of motor involvement, which seem to
progress.
Intermittent cognitive and behavioral status changes are often observed and also seem to progress with the severity
of the disease. This is often referred to as “brain fog” by the patient as they experience waxing and waning of
this symptom.
Laboratory findings in these patients are variable but often reveal eosinophilia and elevated levels of
immunoglobulin E.
Other symptoms of varying severity and frequency have been described.
These researchers are making a case for this disease and cautioning practitioners not to simply diagnose delusional
parasitosis, as there are more symptoms, which need further investigation and explanation. The Center for Disease
Control (CDC) has recently launched an epidemiological investigation into this emerging disease due to the
increased number of reports (up to 5000 in the United States to date).11,12

CASE REPORT
A 61-year-old white woman presented to her periodontist for treatment of an oral lesion of 2-years duration. She
has a history of hyperthyroidism and osteoporosis (she is taking Fosamax for her osteoporosis). She has an allergy
to latex and Inderal. At age 20, she had mononucleosis and hepatitis. She reports that she travels a lot. She is
otherwise healthy with no other symptoms (no neurologic symptoms or skin lesions).
The patient's periodontist reports a solitary oral lesion on the mucosa distal tuberosity of tooth 2. No intraoral
photographs are available, nor was the area biopsied. The periodontist reports a small amount of bone breakdown in
this area. No other oral lesions or skin lesions are reported. There is no pain, inflammation, or other sensations,
and there is no history of surgery in this area.
The patient reports the emergence of very fine fibers from this lesion over the past 2 years, “numerous fibers.”
The patient estimates 10-20 fibers from this lesion over the period reported. She complains of intense itching and
irritation from this area and is constantly scratching the area with her finger (verbal consult with the
periodontist).
Three fibers were removed and sent to pathology, 1 placed in formalin and 2 attached with adhesive tape to a paper
card. The fibers were removed by the periodontist with cotton pliers from the lesion. The surrounding soft tissue
has not been biopsied. On numerous occasions, the patient has removed fibers as well. They were submitted with a
laboratory requisition form that contained a short clinical history and the provider's name.

PATHOLOGY REPORT
Each of the 3 fibers submitted for pathology are approximately 2.5 cm in length and the same diameter as a human
hair. Under light microscopy, the fibers appear to be of the same shape and size as a human hair fiber. The shaft
of the fiber is not as uniform in diameter as a hair fiber. They are monofilaments that are generally nonpigmented
and clear, but they do have some inclusions and they have tapered rounded ends. They do not appear the same as hair
fibers under polarized light. They polarize differently than human hair and present as a synthetic monofilament
(Fig. 1).
Figure 1
Image ToolsThe 2 fibers taped to a paper card were sent to Arizona State University for scanning electron
micrographs (SEMs) and analysis (Figs. 2, 3). They reveal monofilaments with little microstructure and a homogenous
cross section. They are irregular in diameter along their length and reveal some artifact due to handling (a
flattened spot where the fibers were clamped).

Figure 3
Image Tools
The spectrum profile shows predominantly carbon based with a small amount of oxygen. A small artifact was produced
with a spike at Au (gold), which is used to make the object conductive for the electron microscope. There are no
other elements visible on this spectrum profile. The single fiber in formalin is retained and archived for future
investigation.

DISCUSSION
Bight field and polarized light microscopy show a monofilament that lacks pigmentation. It has a slightly
nonuniform diameter along its length. It polarizes differently than a human hair and presents as a synthetic fiber
with a knurled surface appearance refracting the polarized light in a uniform pattern. This is consistent with a
synthetic fiber of some type of polymer.
SEMs show a monofilament with little microstructure (Figs. 2, 3). It appears homogenous in cross section and is not
of uniform diameter along its length. It appears deformed and flattened in focal areas where it may have been
clamped during handling.
The x-ray spectrum shows a composition of primarily carbon with a small amount of oxygen supportive of a possible
hydrocarbon polymer (Fig. 4). The small spike of gold (Au) is artifact introduced when making the fiber conductive
for the SEM. There are no indications of nitrogen or other elements that would support a protein composition for
this fiber.
Figure 4
Image ToolsInvestigation reveals that these fibers are synthetic and possibly implanted into the tissues by the
patient. This patient did not report any of the other symptoms associated with the Morgellons disease listed above
other than itching and irritation at the lesional site. This supports the commonly held belief that most of these
cases of Morgellons disease are nothing more than delusional parasitosis and should be treated as such. A correct
diagnosis must be rendered before an accepted treatment can be expected to yield some results and alleviate
symptoms. In this case, the findings support a diagnosis of delusional parasitosis due to evidence supporting the
fact that the fibers are synthetic and must have been introduced into the lesion by the patient.
Due to the diverse number of symptoms by patients who experience these skin (and now mucosal) conditions, the CDC
is undertaking a measured and thorough scientific investigation. The CDC is conducting this study along with the
Kaiser Permanente's Northern California Division of Research with the study designed and led by the CDC.
The study will determine the clinical and epidemiological features of this condition looking at skin biopsies from
affected patients, characterizing foreign material such as fiber and threads obtained from patients with this
condition. A summary of findings of the peer review panel will be presented to CDC's coordinating center for
infections diseases Board of Scientific Counselors in November of 2009 and made available on the CDC web site.
