Vocal fold nodule

Japanese: 声帯結節 - せいたいけっせつ（英語表記）Vocal fold nodule

Vocal cord nodules are small nodule-like protuberances that often occur bilaterally in the front third of the vocal cords, where vibration is greatest during speech. They are also known as poet's nodes or singer's nodes, and are often found in people whose jobs require excessive use of the voice. The color of the surface is often almost the same as that of the surrounding normal mucosa, and they can usually be distinguished from vocal cord polyps by the naked eye. They are also found in infants or school children who overuse their voice, and are sometimes referred to collectively as school-age hoarseness or childhood nodules.

Japanese:

発声時に振動の最も大きい声帯の前1/3の部位に，多くの場合両側性に生ずる小さい結節様の隆起を一般に声帯結節という。別名，謡人結節あるいは歌手結節などといわれるように，声を過度に使う職業の者によくみられる。表面の色調は周囲の正常粘膜のものとほとんど変わらないことが多く，通常は声帯ポリープとは肉眼所見からも区別される。また，幼児あるいは学童で声を乱用する場合にもみられ，これらは学童嗄声（させい）あるいは小児結節と総称されることがある。
