title: Neural invasion in intraductal carcinoma of the breast.
abstract: Although perineural invasion in a malignancy favors the diagnosis of invasive over in situ carcinoma, we report a case of cribriform intraduct carcinoma of the breast showing perineural invasion. The in situ nature of the lesion is supported by the finding of an intact actin-positive myoepithelial cell layer around the cribriform growths and the preservation of lobular architecture.
