title: Primary anaplastic giant cell adenocarcinoma of the larynx.
abstract: Anaplastic giant cell adenocarcinoma is an extremely rare tumour arising in the bronchial mucosa. This report describes an example--the first to be reported--of such a tumour evidenced in the subglottic region in a 64-year-old man. Histologically, the tumour resembles that arising in the lung and its morphological characteristics justify a distinction of anaplastic giant cell adenocarcinoma from other types of laryngeal malignant epithelial tumours. As to its histogenesis, the neoplasm is most probably of glandular origin and should be considered as a dedifferentiated adenocarcinoma. The patient, who had undergone total laryngectomy followed by X-ray treatment, is alive one year after surgery.
