[Demodicidosis in humans as a current problem in dermatology].

Demodex mites are common parasites in the hair follicles and in the pilosebaceous glands. Demodex folliculorum and D. brevis have been identified in humans and play a role in three facial conditions: Pityriasis folliculorum, rosacea-like demodicidosis and Demodicidosis gravis. The highly infected sites by this mites are: forehead, area around the orbit, area around the nose, chin and area around the mouth. Infection of the skin by D. folliculorum is more frequent among females and in the elderly people. The presence of mites can be determined by microscopic inspection of secretion from sebum glands and skin surface biopsy. The aim of our study was to report a 25-year-old woman suffering from skin diseases with high D. folliculorum density.
