title: Guttate psoriasis sparing Becker's melanosis--a case report.
abstract: A young man with Becker's melanosis developed typical guttate psoriasis following an attack of tonsillitis. The psoriatic lesions spared the area of melanosis, suggesting that there may be local factors within an area of Becker's melanosis which inhibit the development of psoriasis.
