Abstract

Rhabdomyoma is a benign tumor of striated muscle origin that is very rare in young children. Review of the world literature revealed 20 cases of extracardiac adult-type rhabdomyoma in the head and neck area. All reported cases have been encapsulated and easily excised. A 22 1/2-month-old girl with a parapharyngeal rhabdomyoma is unique in that her tumor had atypical histology and lacked a capsule; it could not be "shelled-out".

摘要

横纹肌瘤是一种起源于横纹肌的良性肿瘤，在幼儿中非常罕见。对世界文献的回顾显示，头颈部区域有20例心脏外成人型横纹肌瘤。所有报道的病例都有包膜，易于切除。一名患有咽旁横纹肌瘤的22个半月大女孩的独特之处在于，她的肿瘤具有非典型组织学特征且没有包膜；无法“完整剥除”。
