title: Cylindroma expresses immunohistochemical markers linking it to eccrine coil.
abstract: Nerve growth factor, S-100 protein, CD44, and CD34 have unique expressions in or surrounding eccrine coil but are not found in eccrine duct or apocrine gland. We studied 15 cases of cutaneous cylindroma to see if these antigens are found in this neoplasm. All were found in cylindroma to varying degrees. These results link the histogenesis of cylindroma to the eccrine coil. A unique feature of cylindroma is the large number of prominent dendritic cells most likely representing Langerhans cells that permeate the tumor aggregates.
