为了解发生于喉腔及喉咽部的平滑肌肉瘤的临床特点，报告1例喉咽部平滑肌肉瘤和2例喉腔平滑肌肉瘤。患者早期症状都不明显，区无特异性，临床表现与该部常见鳞癌极为相似，术前明确诊断有一定困难。因此，治疗应首选大范围手术切除，因早期颈淋巴结转移极少，故对亚临床型淋巴结病变不主张预防性颈淋巴清扫术，放疗可作为辅助或姑息治疗手段。 To understand the clinical features of leiomyosarcoma in the throat and larynx, 1 laryngopharyngeal leiomyosarcoma and 2 laryngeal leiomyosarcoma cases were reported.
