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.
一名患有贝克尔黑素沉着病的年轻男子在扁桃体炎发作后出现了典型的点滴状银屑病。银屑病皮损避开了黑素沉着区域，这表明在贝克尔黑素沉着病区域内可能存在抑制银屑病发展的局部因素。
