Cutaneous Reactions to Aluminum

Abstract

: Cutaneous exposure to aluminum may occur via contact with metal items, medications, and personal care products. Despite the widespread use of aluminum, allergic contact dermatitis is relatively rare. Sensitization is often incidentally identified during patch testing with aluminum-based chambers. This article presents several cases along with a literature review summarizing prevalence and clinical manifestations of cutaneous reactions to aluminum, recommendations for patch testing, sources of aluminum, and reproducibility of aluminum allergy over time.
