化学感受器瘤(chemodectoma)是指颈动脉化学感受器及其同类组织细胞发生的肿瘤。1950年由Mulhgan首次命名报道,又称为颈动脉体瘤(carotid body tumour)或副神经节瘤(paragangliom)。这是一种罕见的肿瘤,仅占全部嗜铬细胞瘤10%~15%~([1])。化学感受器瘤大多为非功能性,以良性居多,仅有5%~10%为恶性,可经淋巴或血行转移至中纵隔及后纵隔的脊柱旁沟,后者相对较多,脊柱转移较为少见,颈椎转移更为罕见。在近30年文献中,国内 Chemodectoma refers to carcinomas that occur in carotid chemoreceptors and their cognate tissue cells. First reported in 1950 by Mulhgan, also known as carotid body tumor or paragangliom. This is a rare tumor, accounting for only 10% to 15% of all pheochromocytoma ([1]). Most chemosensory neoplasms are non-functional, mostly benign, and only 5% -10% are malignant. They can be lymphatic or hematogenous metastasis to the paravertebral canal of the mediastinum and the posterior mediastinum. The latter are relatively more and the spine metastases are rarer , Cervical spine metastasis is more rare. In the past 30 years in the literature, domestic
