颈动脉体瘤(CBT)是发生于颈动脉分叉处的一种少见的内分泌肿瘤,大多数为良性,少数为恶性,由于此病临床上多无特异症状,故诊断困难;此外,因体积较小,周围血管丰富,极易出血,而且出血后很不容易控制,所以手术较困难,术后并发症多。本文就其临床病理特点、发病机制及分子遗传学特点、生物学行为、超微结构以及组织起源等方面的研究进展进行综述,以使大家对这种少见肿瘤有更新更全面的认识。
Carotid body tumor (CBT) is a rare endocrine tumor that occurs in the bifurcation of the carotid artery. Most of them are benign and few are malignant. Due to the fact that this disease is clinically unspecific, it is difficult to diagnose. In addition, Smaller, rich in peripheral blood vessels, bleeding easily, and after bleeding is not easy to control, so surgery is more difficult, postoperative complications. This review summarizes the clinical features, pathogenesis, molecular genetics, biological behavior, ultrastructure and origin of tissue in order to make newer and more comprehensive understanding of this rare tumor.
