“…Skin biopsies may show folliculitis with lymphohistiocytic infiltrates, occasionally with granulomas. 4 Identification of Demodex mites in follicular orifices is supportive but not alone diagnostic of Demodex folliculitis, since these organisms often are incidentally identified in skin biopsies obtained from a variety of unrelated dermatoses. The main role of skin biopsy is to exclude other disorders.…”

“…Given the normal distribution of pilosebaceous structures, Demodex folliculitis often involves the face, scalp, and chest 1,3 . Patients may present with rosacea‐like skin lesions, including blepharitis and/or a pustular eruption, 1 or eruption resembling seborrheic dermatitis 4 . Due to the varied presentations of Demodex folliculitis, high clinical suspicion is often required to make the diagnosis.…”

Demodex folliculorum is a commensal mite that inhabits the orifices of cutaneous pilosebaceous follicles. Overgrowth of these organisms can lead to Demodex folliculitis, which typically presents as papules and pustules predominantly involving the temples, cheeks, and occasionally the chest. We present a 51‐year‐old woman with iatrogenic Demodex folliculitis secondary to immunosuppressive treatment for an autoimmune connective tissue disease. Histopathological exam of a skin biopsy, which revealed follicular Demodex mites, confirmed the diagnosis. The eruption was treated with oral ivermectin and topical metronidazole gel, and the patient's immunosuppressive regimen was decreased, resulting in marked improvement in the eruption within 6 weeks and no worsening of her underlying autoimmune disorder. This case emphasizes the importance of considering Demodex folliculitis in the differential diagnosis of a new onset rash in the context of immunosuppressive treatment.
