Cutaneous Adnexal Cylindroma of Breast: Epithelial Immunoreactivities for GATA-3, Mammaglobin, and E-Cadherin Do Not Equate to a Mammary Ductal Neoplasm

<div>Histopathologic findings: (a) intermediate magnification of “jigsaw pattern” with biphasic cell nests showing outer somewhat palisaded small blue cells and central basaloid cells with slightly more abundant eosinophilic cytoplasm as well as fibrous stroma, H&amp;E stain, 200x; (b) basement membrane material investing periphery of epithelial nests, PAS stain, 200x.</div>
