Carotid body tumors (CBTs) are rare neoplasms of the carotid body. Most CBTs are benign; however, some can show malignant behavior. Malignant CBTs have an unpredictable history; often, there is no correlation between the histologic findings and the clinical behavior. They are usually diagnosed by the development of local recurrence or lymph node metastasis following total resection of the primary mass, or by the detection of distant metastasis. There are few reports of histopathologic confirmation of malignant CBTs. We report a rare case of malignant CBT with distant metastases, in which the diagnosis was confirmed by histopathology, and present a review of the literature.
颈动脉体瘤（CBTs）是颈动脉体的罕见肿瘤。大多数CBTs是良性的；然而，有些可能表现出恶性行为。恶性CBTs的病程难以预测；通常，组织学检查结果与临床行为之间没有相关性。它们通常通过在原发肿块完全切除后出现局部复发或淋巴结转移来诊断，或者通过检测远处转移来诊断。关于恶性CBTs经组织病理学证实的报道很少。我们报告了一例罕见的伴有远处转移的恶性CBTs病例，其诊断经组织病理学证实，并对相关文献进行了综述。
