Patch-Testing North American Lip Dermatitis Patients: Data from the North American Contact Dermatitis Group, 2001 to 2004

Abstract

Patch testing is valuable in the evaluation and identification of contact allergy in patients referred for lip dermatitis. The use of supplementary allergens based on history and exposure is important in the identification of additional relevant allergens. Over a third of patients with contact allergy had other factors, such as irritant dermatitis, considered relevant to their condition.
