Case History

 

Last month the Cooperative Extension Service referred a client from the Midlands to the Agromedicine Program.  He complained that his skin was infested with mites. He discussed his illness several times with Dr. Schuman and Dr. Simpson during the next several weeks.

 

The patient reported itching of his scalp, ears, arms and legs for the past four months. The itching was so severe that he was not able to sleep at night. The mites had followed him and his family from one house to another. He had his new home treated several times by a pest control company without relief. He has now started applying insecticides himself in an effort to rid the home of mites. Other family members and pets were unaffected by the mites.

 

The patient had been examined and treated by his family physician and a dermatologist. Both doctors treated the patient for dermatitis of unknown origin; however the itching only increased in severity.  The patient lost confidence in both physicians. He sent numerous skin scraping samples to university entomologists who did not observe mites or any other insects.

 

Dr. Schuman thought this might be a case of early delusory parasitosis. This is a condition in which patients Dr. Stanley Schuman (center) was awarded the Order of the Palmetto on November 3, 2000 in recognition of his statewide public service through the Agromedicine Program. Mr. Nick Theodore (right), senior counsel to Governor Hodges, presented the award to Dr. Schuman at the 50th annual meeting of the S.C. Cattlemen's Association held in Greenville, S.C. Dr. Victor Cornett (left), president of the association, nominated Dr. Schuman. Photo by Danny Howard. have a strong false belief that they are infested with parasites. These patients typically seek treatment from a series of physicians and entomology specialists.  They use extreme methods (repeated insecticide applications, showering numerous times daily, moving, etc.) to rid themselves of the insects. Dr. Schuman scheduled the patient to see a MUSC dermatologist experienced in treating this type of case with success.

 

Prior to the appointment, the patient began searching the Internet and medical databases for cases similar to his. He learned that delusory parasitosis is treated with the psychotropic medication, pimozide. After learning this, he telephoned our office to cancel the appointment with the dermatologist and stated that he did not have a psychosis.

 

Patients with this disorder usually resist treatment after learning that pimozide is a psychotropic medication. The medical literature1 has shown pimozide to be an effective treatment, here and overseas.
