Usefulness of Skin Testing for Rosacea-like Dermatitis: Clinical Analysis of 71 Cases

Abstract

We retrospectively analyzed 71 cases of rosacea-like dermatitis who had undergone skin testing at our hospital between January 2001 and October 2012. The group included one male and 70 females, and had a median age of 52 years. Approximately 40% of the patients were suspected of having contact dermatitis, but had not undergone skin tests. As a result of the skin tests, we diagnosed 70% of the patients (52 cases) as having allergic contact dermatitis; 32 of those cases were caused by cosmetics. Skin testing is a useful tool for investigating the cause of rosacea-like dermatitis and for deciding on appropriate treatment, because many patients with rosacea-like dermatitis actually have contact dermatitis.
