Two cases of extracardiac rhabdomyoma are reported in a 54-year-old man with unexplained difficulty in breathing and in a 39-year-old man with a prolonged history of hoarseness. Attention is drawn to the necessity of doing hypopharyngo-and laryngoscopy in such cases. One tumour was found in the left vallecula in the hypopharynx and the other on the left vocal cord. The literature and the histological findings in 53 cases are reviewed. It appears that this rare tumour is most frequently found in muscles derived from the pharyngeal arches. A total of 40 cases have been diagnosed during the last decade, and this increase is likely to continue in the future. It may turn out that extra-cardiac rhabdomyoma is not so rare as was first presumed.
本文报告了两例心脏外横纹肌瘤病例，一例为一名54岁有不明原因呼吸困难的男性患者，另一例为一名有长期声音嘶哑病史的39岁男性患者。文中提请注意在此类病例中进行下咽和喉镜检查的必要性。其中一个肿瘤位于下咽的左会厌谷，另一个位于左侧声带。对53例病例的文献及组织学发现进行了综述。结果显示，这种罕见肿瘤最常见于源自咽弓的肌肉中。在过去十年中总共诊断出40例病例，且这种增长趋势在未来可能会持续。结果可能表明，心脏外横纹肌瘤并不像最初认为的那么罕见。
