Syringoma of the eyelids and the disseminate type called "eruptive hidradenomas" are well known. We saw three patients with syringoma of the vulva. To our knowledge, these are the first cases reported in the English literature. Since all three cases came from one gynecologist's office practice, vulvar syringoma may be more common than is generally recognized.
