摘要


心臟外的橫紋肌瘤,是相當罕見的良性腫瘤,較常發生在頭頸部的軟組織中,根據病理基因學,頭頸部的橫紋肌瘤被認爲是起源於第三和第四鰓弓的橫紋肌。喉橫紋肌瘤,其主要症狀與其他喉部腫瘤相似,常見漸進式聲音沙啞和喉異物感,手術前不易被診斷出來。本文報告一患者因喉部腫瘤接受喉正中切開術,治療之後經由組織病理切片檢查,及肌源標誌的免疫生化染色,證實爲罕見的成人型喉橫紋肌瘤。患者術後於門診追蹤2年,聲音品質恢復良好,無局部復發現象。

Extracardiac rhabdomyomas are rare benign tumors that most frequently affect the soft tissues of the head and neck region. According to the pathogenesis, rhabdomyoma in the head and neck region are believed to originate from skeletal muscle of the third and fourth branchial arches. This report of a patient with laryngeal rhabdomyoma presented with symptoms of persistent progressive hoarseness and a foreign body sensation in the throat. It is difficult to identify tumor nature prior to surgical intervention. Laryngofissure was used to excise the tumor totally. The histopatho logical examination and immunohisto-chemistry stain with a myogenic marker indicated an adult laryngeal rhabdomyoma. Postoperative videostroboscopy in the outpatient department indicated no recurrence of tumor with good voice quality.
