Demodicidosis is a skin infection that often affects the face, but may affect other areas, caused by Demodex mites. Demodex mites are usually harmless, but may cause inflammation when present in large numbers or when they penetrate the skin. Demodicidosis is more often seen in individuals with immune suppression, such as those suffering from HIV or certain cancers, but it can also present in individuals of good health.
Demodicidosis often causes severe itching (pruritic), reddening and irritation (erythematous), and blistering or pimpling of the skin (papulopustular lesions). Diagnosis of demodicidosis may require a skin surface sample (biopsy), or other methods that show the presence of the Demodex mite. Treatment generally requires oral medications. If you are experiencing frequent or unmanageable skin irritation, redness, and lesions, talk to your doctor about Demodicidosis and the most current treatment options available.
