Chronic relapsing allergic contact cheilitis from a toothpaste. A case report.

: The paper describes the case of a 25 year-old caucasian man whose cheilitis was initially erroneously diagnosed and treated as herpetic cheilitis, and was then correctly identified as a toothpaste allergic contact cheilitis. The remission of the pathology was achieved through the elimination of the allergen, while the clinical symptoms were controlled by means of topic application of corticosteroids, with a complete and stable restitutio ad integrum of the perioral tissues.
