The author, describes the Actinic Dermatitis and a syndrome that he named "Sindrome cutáneo guatemalense" SCG (Guatemala's Cutaneous syndrome). Its has been studied and found in 98;5% of more than a thousand patients studied since 1957. He considered the SCG a patognomonic syndrome and of practical importance in the positive and differential clinical diagnosis of Actinic dermatitis with the other photodermatoses of the face, neck and "V" of the chest.
