title: Eccrine Syringofibroadenomatosis of the Soles.
abstract: Eccrine syringofibroadenoma is a rare adnexal tumor with acrosyringeal differentiation. It was first described by Mascaro in 1963. Its clinical presentation varies from a solitary nodule, keratotic papule, verrucous plaque, or palmoplantar keratoderma to multiple lesions with linear or diffuse distributions. Age at onset ranges from 16 to 80 years. Lesion distribution is wide and includes the face, back, abdomen, buttocks, extremities, and, rarely, nails. There are five subtypes of eccrine syringofibroadenoma. Histologically, eccrine syringofibroadenoma, independent of the subtype, is characterized by anastomosing cords of acrosyringeal cells forming ductal structures in a fibrovascular stroma and attached to the undersurface of the epidermis in multiple foci. In this article, we describe a 51-year-old woman diagnosed as having eccrine syringofibroadenomatosis.
