Three Cases of Acneiform Demodicidosis due to Long - Term Application of Corticosteroid Ointment / 대한피부과학회지

ABSTRACT

Demodicidosis is caused by the enormous infestation of 400 micron sized demodex folliculorum which normally exist, though in small number, in pilosebaceous unit. Its characteristic clinical feature is erythema and erythematous indurated papulopustular eruptions combined with itching and buming sensation. Microscopic examination of indurated pustule always reveals demodex folliculorum. Many authors have reported that demodicidosis aggravated by avoidance of using soap, long-term use of cosmetic cream, especially cold cream, topical or systemic use of corticosteroid. Our patiednts were housewives of 46,39, and 42 years old and presented characteristic clinical featurss and skin lesions by topical application of corsicosteroid for 1~2 years and were diagnosed as steroid acne. But simple microscopic examination reveled demodex folliculorum. We treated them with 5% sulfur lintment and soap and water cleansing of face with remarkable clinical improvement.
