原発性喉頭肉腫2症例

抄録

Two cases of sarcoma of the larynx were reported. One was a 78-year-old man who was admitted to hospital in November, 1968 with marked hoarseness and stridor. Laryngoscopy revealed a tumor of the left vocal cord and false cord which had spread to involve the arytenoid. Section showed a reticulum cell sarcoma. Total laryngectomy was performed and he has been well for three years. The other patient was a 27-year-old woman who had complained of hoarseness for 15 months was seen in May, 1965. She was found on examination to have a tumor of the larynx which showed to be a lymphosarcoma and had been treated with ⁶⁰Co 5200 rads. At present she is well six years after radiation. Both primary tumors were considered to arise in the submucous lymphoid tissue of the laryngeal ventricle. Biopsy of sarcoma of the larynx occasionally does not succeed, because the surface of the tumor is mostly covered with normal mucous membrane or nectrotized mass. The radiation therapy of malignant lymphoma of the larynx is better than resection, but the other kind of sarcoma should be surgically treated.
