Endotracheal neurilemoma with a lymphoid cuff. An ultrastructural and immunohistochemical study.
A neurilemoma occurred in the trachea of a 63-year-old woman complaining of dyspnea. Microscopically, the excised tumor was composed predominantly of cellular areas of Antoni type A tissue and had a peripheral lymphoid cuff. The schwannian origin was confirmed both immunohistochemically and ultrastructurally. This tumor without nuclear palisading and Verocay bodies differed somewhat from a conventional soft tissue neurilemoma and closely resembled a particular form of neurilemoma of the stomach, previously reported as a unique entity. Thus, this type of neurilemoma does occur in sites other than the gastrointestinal tract.
