喉頭の神経線維腫の1症例

Neurofibroma of the Larynx: Report of A Case

I．緒言

　喉頭に発生する良性腫瘍については，乳頭腫，線維腫，嚢腫，腺腫，粘液腫，軟骨腫，リンパ管腫，血管腫などが，現在までに種々報告されているが，神経原性腫瘍は比較的稀とされている。今回私共は，呼吸困難を主訴とし喉頭蓋左側縁に茎を有する神経線維腫の1例を経験し，局麻下経口的に摘出しえたので若干の文献的考察を加えて報告する。

　A rare case of the laryngeal neurofibroma in a 31-year-old man complaining of severe dyspnea was reported. Direct laryngoscopy revealed a large smooth mass occupying the laryngeal space and its steal was found arising from the left epiglottic edge. The movement of the vocal cords was intact bilaterally. The tumor was successfully removed under local anesthesia by oral approach and it was 3.5 × 2.0 × 2.0mm in size and 16.0g in weight. Histopathological examination showed spindle cells proliferating in a palisade pattern, suggesting neurofibroma. It was also found that the spindle cells occasinally proliferate in a myxoid struma.

　The patient's postoperative course was satisfactory. Postoperative laryngeal function was normal and no reccurence was observed.
