5歳幼兒に發生せる鼻咽腔淋巴上皮腫の1例

　緒言

　淋巴上皮腫瘍は1921年シユミンケが初めて5例を報告したもので，一名シユミンケの腫瘍とも称せられる．本邦に於ては昭和12年に緖方，平山両氏が，17歳の男子で肝臟脾臟其の他に轉移を認めた鼻咽腔の巨大なる淋巴上皮腫の1例を報告したのが最初で，私が文献を渉獵した範囲では，其の後数例の報告を得ただけである．

　私は最近5歳の幼兒に発生した鼻咽腔腫瘍を経驗し，病理組織学的檢索の結果，シユミンケの言う所の淋巴上皮腫であることを認め，レントゲン深部治療，ラヂユーム照射等によつて一時は非常に良好な経過を辿つたが，其の後約1ケ月で再発し急速な腫瘍の増殖のため，遂に不幸な轉帰をとつた症例に遭遇したのでここに其の臨床経過を報告する．

Amagishi reports that lympho-epithelioma was the cause of nasal obstruction, in a remale child 5 years of age, for which the relief was sought as the patient's chief complaint. Ex-amination revealed a tumor in the nasopharynx and with biopsy of this mass it was shown to be a lympho-epithelioma under the microscope. Relife of obstructive symptoms were attained for a period of time following surgical removal of the growth and irradiation of the area by application of deep roentgen rays and radium. But, a month later all symptoms returned by causing obstruction of both nasal cavities and, the greater part of nasopharynx with evidence of metastatic enlargement of lymphatic tissues in the surrounding area. It appeared that meta-stasis of the tumor also occurred in the left maxillary sinus and possibly in the base of the skull. The patient died.
