Secondary tumours of the hyoid bone and thyroid cartilage are extremely rare. In this paper, we present a case of the hyoid bone and thyroid cartilage metastases in a patient treated for sigmoid colon adenocarcinoma.
Four years after sigmoid colon adenocarcinoma was diagnosed and treated with surgery and chemotherapy, the patient developed bone metastases in the left sacroiliac joint and right proximal humerus. Although the patient did not complain of any related symptoms, in a bone scintigraphy the accumulation of Technetium-99m was incidentally detected in the two sites of the anterior neck. On ultrasound examination there were two hyperechoic and heterogeneous masses with calcifications placed in front of the hyoid bone and thyroid cartilage. Computerized tomography demonstrated massive hyoid bone and thyroid cartilage destruction.
In patients with progressive sigmoid colon adenocarcinoma, destruction of the hyoid bone and thyroid cartilage could be suspected for metastases.
舌骨和甲状软骨的继发性肿瘤极为罕见。在本文中，我们报告了一例乙状结肠腺癌患者发生舌骨和甲状软骨转移的病例。
乙状结肠腺癌经手术和化疗诊断及治疗四年后，患者出现左骶髂关节和右肱骨近端骨转移。尽管患者未诉任何相关症状，但在骨闪烁显像中，偶然在前颈部两个部位检测到锝-99m的聚集。超声检查发现舌骨和甲状软骨前方有两个高回声、不均匀且伴有钙化的肿块。计算机断层扫描显示舌骨和甲状软骨大量破坏。
对于进展期乙状结肠腺癌患者，应怀疑舌骨和甲状软骨破坏为转移所致。
