title: Cervical schwannoma with intranuclear vacuoles by fine-needle sampling without aspiration.
abstract: In a 49-yr-old woman who presented with a cervical mass, a fine-needle specimen without aspiration was suggestive of paraganglioma; there were spindle-shaped cells with pseudoacinar structures and prominent intranuclear vacuoles. Subsequent examination of a mass removed from the vagus nerve clearly identified a schwannoma. The differential diagnosis is discussed, particularly in relation to the presence of intranuclear vacuoles, and it is concluded that this cytological characteristic should not in itself define the diagnosis.
