I wrote previously on NeuroLogica blog about Morgellons disease. Both Peter Lipson and Wallace Sampson have also covered this interesting syndrome here on SBM. Briefly, sufferers of this dubious syndrome believe they have foreign material exuding from their skin, causing chronic itching and sores. The evidence suggests that in truth they suffer from something akin to delusional parasitosis – the false belief of foreign parasites in their skin, leading to chronic itching which causes the sores and also works clothing fibers into the skin, which are later exuded.
Morgellons, in short, is a fake disease, a false and somewhat far-fetched explanation for symptoms that have a much more prosaic, if undesired, explanation.
Those who believe they have Morgellons, however, are legitimately ill and are an extremely vulnerable population. They feel they have a serious and mysterious illness, and worse the medical profession does not understand their illness and so denies that it exists. This is a perfect setup for snake oil-peddling con-artists.
