Laser Recall Dermatitis

Laser Recall Dermatitis Chemotherapy-induced recall dermatitis is a phenomenon whereby the administration of a chemotherapy agent induces an inflammatory reaction at sites injured previously, days, months, or even years earlier.1 Radiation recall dermatitis, where the inflammatory reaction appears at a previously irradiated site, and reactivation of UV light–induced erythema after methotrexate therapy are the prototypes of recall phenomena. A few cases of chemotherapy recall phenomenon on a site of drug extravasation and on a previously scalded wound have been reported.1,2 The concept of recall dermatitis is not exclusive for chemotherapy drugs and may also be induced by tuberculostatic drugs, antibiotics, and simvastatin.3
