我が教室に於ける鼻咽腔腫瘍の觀察

　緒言

　昭和10年から約15箇年の間に我が教室を訪れた38例の鼻咽腔腫瘍患者に就いて，それらの臨床症状，治療，治療方法と豫後との關係を檢討して見たいと思う．例數が少ないので決定的な事は云えない．他教室の方の補足を希望する．

OGINO reports of his clinical obsesvatios on 38 cases of nasopharygeal tumors which he had encoun-tered in the last 15 years. Nasopharygeal fibromas, characterized by nasal obstructions and epistaxis, are apt to occur more frequently in male adolescents, especially between the ages 15 to 20, than in females. Prognosis of fibroma is very favorable when treated by means of operation and radium irradiation. On the other hand the prognosis of nasopharygeal cancer, the most characteristic features of which are headache, deafness and paralysis of the V, VI, and Ⅶ cranial nerves, that at the time of admission to the hospital may not show evidence of cervical gland metastasis but may develop later in the course of the disease, is usually poor. Nasopharygeal sarcoma with fibroma constiuted a fairly large proportion of all tumors in this area and 77 per cent of the former were that of reticular cell type. Endothelioma was found in 1 case only.
