頸静脈小体腫瘍（総説）

　I．命名について　この病名の腫瘍は数年前に米国に於いて発見されてからは，殊に同国では続々と症例が追加されて文献と共に研究内容も豊富となつている。我国では未だ一例も報告が無いようだ。最近私は本症に実によく似た症例を経験した（その病名は耳部軟骨肉腫症で次章に発表した）機会にこの腫瘍について米国文献を調べて知つた所を綜説として述べる。

　この腫瘍に対する命名は未だ決定したものが無いようで，米国では次の3通りが使用されている。

The tumor of glomus jugulare is manifested by tumor formation of the glomus jugulare which is similar to other carotid bodies and is situated attached to the bulbus jugulare as a normal structure. Because of its situa-tion it may appear to cause tumefaction of the mastoid tip or the tumor may invade the middle ear or other temporal bone structures :specific symtoms may be manifested by cau-sing paralysis of the glossopharygeus and sympathetic nerves. The diagnosis of the condition is reached by making microscopic examination of the glomus jugulare to show the presence of tumor cells.

Attention to this condition has been enpha-tically called for the first time in American literatures with reports of number of cases but, the roports in the literature of this cou-ntry are yet to be seen. The present article is intended to be an introduction to this disease.
