Nine cases of perioral dermatitis and 16 cases of rosacea-like dermatitis have been treated for the last 3 years at our clinic. These cases were all females whose ages ranged from 18 to 61 years with a mean of 45 years. All had been under treatment with fluorinated steroids for a period of from 3 months to 10 years, about 3 years on the average. Tetracyclines were beneficial as remedies for these conditions, bringing about healing or remission in approximately 3 months. About 1 year was required for the recovery from atrophy of the skin and telangiectasia. Hydrocortisone 17-butyrate was more useful as a topical medication than hydrocortisone acetate but gave rise to withdrawal rebound eruptions in some cases.
