Rosacea is a chronic skin disease affecting the facial area. The causative agents are unknown. Demodex mites can cause rosacea in human beings.

Case Presentation:

In this article five cases of rosacea due to Demodex folliculorum are reported. The first case was a 26-year-old male wrestler. The second case was a 4-year-old-boy with immunodeficiency syndrome, the third case was a 29-year-old lady, the fourth was a 7-year old boy and the fifth was a 36-year-old female. All patients were suffering from erythema, itching, inflammation and in some cases acne-like pustules in their face. The first case was suffering from lesions on his neck as well. All patients were referred to the Iran-Zamin diagnostic laboratory for fungal examination. Scraping from the lesions and slide preparation in 20% KOH and microscopic examination revealed D. folliculorum. Scotch tape examination of the lesion on the neck of the first patient indicated the tinea versicolor. The patients referred to dermatologists for treatment.


Clinical similarities of rosacea, fungal diseases and demodicosis might cause unsuitable therapy. Pretreatment examination and identification of disease agent lead to the appropriate management and treatment of the patients.
