There are two species of this mite that cause disease in  humans, including Demodex folliculorum, which is known as hair follicle mite, and Demodex brevis. This disease is more  common in women than in men.  
  Case Presentation: The patient is a 36-year-old woman living in one of the villages of Tabriz city who referred to a dermatologist  following severe itching and hyperkeratosis (abundant dandruff) of the cheeks. Then, she was introduced to the laboratory  for preparing a slide from a sample taken from the patient’s cheeks. A large number of Demodex mites were observed in the  microscopic test of the sample.
