A girl with the characteristic abnormalities of Larsen's syndrome is presented. A soft flabby consistence of the cartilaginous skeleton of the larynx and trachea was thought to be the cause of attacks of respiratory failure which suddenly caused her death at the age of 9 months. Microscopy revealed a considerably reduced number of elastic fibres in the larynx, trachea and bronchi. Closed reduction of the knee dislocation by skin traction seemed to be successful.
本文报告了一名患有拉森综合征特征性异常的女孩。喉和气管软骨骨架质地柔软、松弛，被认为是导致呼吸衰竭发作的原因，该患儿在9个月大时突然因呼吸衰竭死亡。显微镜检查显示，喉、气管和支气管中的弹性纤维数量显著减少。通过皮肤牵引对膝关节脱位进行闭合复位似乎取得了成功。
