Demodicidosis may present as pityriasis folliculorum, papulopustular lesions, rosacea-like eruptions, and granulomatous rosacea-like eruptions. We report a case of demodex granuloma presenting with recurrent granulomatous rosacea-like papules on the face in a middle aged woman. The diagnosis of demodicidosis was made by finding extrafollicular mites in the perifollicular inflammatory infiltrate. The papules resolved after 3 weeks of systemic and topical metronidazole, and low-dose of oral prednisolone therapy. In summary, demodex granuloma may be mistaken for granulomatous rosacea-like papules. Correct diagnosis can be facilitated by finding extrafollicular demodex mites in skin biopsy specimens.
