Localized vulvar syringomas.

Syringomas are benign appendageal tumors with differentiation toward the intraepidermal portion of the eccrine sweat duct. A 35-year-old black woman with lesions confined to the labia majora is presented. Syringomas involving the genitalia are rare, and usually the genital tumors are part of a more generalized distribution. A review of English literature showed only four reported cases of syringomas limited to the vulva. Vulvular syringomas present as multiple, bilateral, skin-colored papules over the labia majora that may or may not be pruritic. The lesions should therefore be considered in the differential diagnosis of multiple papular lesions of the vulva and are probably more common than is generally recognized.
