Sarcomas are a rare occurrence accounting for roughly 1% of all cancer cases reported. Of these, 9-18% will be identified as liposarcoma. Overall, only 4-9% of all liposarcomas occur in the head and neck region. As such, it is a rare event to see a primary liposarcoma of the aerodigestive tract. These tumors are typically misdiagnosed secondary to their indolent, asymptomatic course and similarities in appearance to other benign lesions. An understanding of these lesions will help clinicians appropriately manage their patients. We present a case of a 60-year male with a primary supraglottic myxoid liposarcoma, and provide relevant information about liposarcomas.
肉瘤较为罕见，约占所有报告癌症病例的1%。其中，9% - 18%将被确诊为脂肪肉瘤。总体而言，所有脂肪肉瘤中仅有4% - 9%发生于头颈部区域。因此，发生于气消化道的原发性脂肪肉瘤实属罕见。这些肿瘤通常因生长缓慢、无症状以及外观与其他良性病变相似而被误诊。了解这些病变将有助于临床医生对患者进行恰当的治疗。我们报告一例60岁男性原发性声门上黏液样脂肪肉瘤病例，并提供有关脂肪肉瘤的相关信息。
