Disseminated early yaws: report of a child with a remarkable genital lesion mimicking venereal syphilis.

A 3 1/2-year-old boy, born and living in Indonesia, experienced disseminated skin lesions and an ulcerated, crusted, papillomatous lesion on the prepuce of his penis. This location suggested venereal syphilis, but on clinical, serologic, and epidemiologic grounds a diagnosis of early yaws was made. This treponemal disease should be considered in children who have traveled to or migrated from remote tropical regions, and who have unusual skin lesions in combination with a positive treponemal serology. Although yaws is considered a rare and exotic disease in the United States and Europe, it is still widespread in some parts of the world.
