A neurilemoma occurred in the trachea of a 63 year old woman complaining of dyspnea. Microscopically, the excised tumor was composed prodominantly of cellular areas of Antoni type A tissue and had a peripheral lymphoid cuff. The schwannian origin was confirmed both immuno‐histochemically 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. Acta Pathol Jpn 39:407 412, 1989.
