Demodicosis Treatment with Systemic Ivermectin.

A 23-year-old white man presented to our dermatology department complaining of pruriginous and erythematous papulopustules on the right cheek that had developed 6 months previously. He had a history of chronic blepharitis, complicated by a recurrent hordeolum that had been treated with warm compresses and topical antibiotic ointment (chloramphenicol) for approximately 2 years. The patient had oily skin and atopy (allergic rhinitis) and did not experience photosensitivity or flushing or have previous exposure to immunosuppressants or topical/systemic corticosteroids.
