Syringoma with lesions limited to the penis occurred in a 30-year-old man. Syringomas involving the genitalia are rare, and usually the genital tumors are part of a more generalized distribution. Limitation of the lesions to this site appears unique. Syringoma should be considered in the differential diagnosis of papular lesions of the penis.
