The most common signs of a malignancy in the region of the head and neck are evidence of a mass or symptoms arising from it. In this report a patient is described with rhabdomyosarcoma of the mandible. An incidental x-ray taken some 3 months prior to the onset of clinical symptoms showed no evidence of bone involvement of the mandible. The onset of bone destruction of the angle and ascending ramus of the mandible as seen on a subsequent x-ray can be placed somewhere in this period of time.
头颈部区域恶性肿瘤最常见的体征是肿块迹象或由肿块引起的症状。在本报告中，描述了一名患有下颌骨横纹肌肉瘤的患者。在临床症状出现前约3个月拍摄的一张偶然的X光片显示下颌骨没有骨受累的迹象。随后X光片上显示的下颌骨角和升支的骨质破坏开始时间可确定在这段时间内的某个时候。
