BACKGROUND
Tumors of smooth muscle origin are rare in the upper aerodigestive tract, due to the paucity of smooth muscle in the area. A review of the literature revealed 34 reported cases of leiomyoma, 9 cases of leiomyosarcoma, and only 2 cases of epithelioid leiomyoma arising in the larynx.
METHODS
A case report of an epithelioid leiomyosarcoma arising in the right piriform fossa of a 38-year-old man is presented.
RESULTS
The tumor was treated with conservative surgical resection and postoperative radiotherapy. There was no evidence of locoregional recurrence 2 years postsurgery, and laryngeal function was preserved.
CONCLUSIONS
To our knowledge, this is the third case of a laryngeal epithelioid smooth muscle tumor to be reported in the world literature and the only documentation of an epithelioid leiomyosarcoma arising in the larynx.
背景
由于上消化道气道区域平滑肌数量稀少，平滑肌源性肿瘤在上消化道气道区域较为罕见。文献回顾显示，有34例平滑肌瘤、9例平滑肌肉瘤的报道，而起源于喉部的上皮样平滑肌瘤仅有2例。
方法
本文报告了一例38岁男性右侧梨状窝上皮样平滑肌肉瘤的病例。
结果
该肿瘤采用保守性手术切除及术后放疗进行治疗。术后2年无局部区域复发迹象，且保留了喉功能。
结论
据我们所知，这是世界文献中报道的第三例喉部上皮样平滑肌肿瘤，也是喉部起源的上皮样平滑肌肉瘤的唯一记录。
