title: Fine-needle aspiration cytology of a membranous basal cell adenoma arising in an intraparotid lymph node.
abstract: The so-called membranous basal cell adenoma is a rare subtype of monomorphic adenomas that usually presents in the parotid gland. The cytologic, histologic, and immunohistochemical findings of an example of this entity, arising in an intraparotid lymph node of a 75-yr-old woman, are reported. Only 7 cases of this tumor have been published in such a peculiar location. As far as we know, fine-needle aspiration cytology has never been performed.
