Rosacea and Demodex: A Comprehensive Case Study Validated by Dermoscopy

Abstract

Human Demodex, a widely known ectoparasitic mite, affects mainly pilosebaceous units of the face and head. Human Demodicosis is a skin disease that develops when the follicles become heavily infested, or when the mites penetrate the dermal tissue. Here we have reported a 38-year-old female, who was presented with persistent erythema of the nasal bridge accompanied by pustules. Dermoscopic examination revealed Demodex tails and Demodex follicular openings both specific features of this entity. Histopathological features of skin biopsy were consistent with rosacea in the context of infection with Demodex folliculorum.
