Cervical chondrocutaneous branchial remnants (CCBRs) are rare masses located in the anterior region of the neck. Though the basic characteristics of these rare masses were first described by Atlan in 1997, a critical amount of information about these masses remains unknown. This study aimed to further clarify the characteristics of these rare masses.
We retrospectively reviewed the clinical records of patients with CCBRs in our facility during a 32-year period ranging from 1988 to 2019. We then compared our clinical records with other case reports.
There were 29 patients with CCBRs in our facility, including 19 males and ten females, Three patients were involved bilaterally (among patients involved unilaterally, the right side included 11 patients, and the left side was 15 patients), eight patients also had associated abnormalities. We submitted CCBRs from 18 patients to pathology, and all of them contained elastic cartilages. Among all the surgical data could be confirmed, cartilages did not reach beyond the musculature of the neck. We could confirm a similar tendency with Atlan regarding sex, the location of CCBRs (involvement side, localization in the neck), and the depth of CCBRs. Among the cases contained in this study, there was a disparity in the rate of associated abnormalities and pathology of contained cartilages.
Some critical characteristics of CCBRs included, a male predominance, scarcity of bilateral cases and common left side involvement among unilateral involved cases, a common location of CCBRs in the inferior third of the neck and anterior to the sternocleidomastoid muscle, and an involvement of cartilage in CCBRs which has no connections to deep underlying structure of the neck. Further investigations are required to determine the origin of CCBRs and the precise incidence of the associated abnormalities. Systemic examination in patients with CCBRs is recommended because many associated abnormalities have been reported.
颈皮支鳃裂残余物（CCBRs）是位于颈部前区的罕见肿块。尽管这些罕见肿块的基本特征于 1997 年由 Atlan 首次描述，但关于这些肿块的大量信息仍不为人知。本研究旨在进一步阐明这些罕见肿块的特征。
我们回顾性分析了 1988 年至 2019 年 32 年间我院 CCBRs 患者的临床资料，然后将我们的临床资料与其他病例报告进行了比较。
我院共收治 29 例 CCBRs 患者，其中男 19 例，女 10 例。3 例为双侧病变（单侧病变中，右侧 11 例，左侧 15 例），8 例合并其他异常。我们对 18 例患者的 CCBRs 进行了病理检查，均含有弹性软骨。所有可证实的手术资料均显示，软骨未超出颈部肌肉。我们可以确认 CCBRs 的性别、位置（累及侧、颈部定位）和深度与 Atlan 的结果相似。在本研究包含的病例中，合并异常和含软骨的病理存在差异。
CCBRs 的一些关键特征包括男性居多、双侧病变罕见、单侧病变常见左侧受累、CCBRs 常见于颈下部和胸锁乳突肌前、CCBRs 中软骨无与颈部深部结构相连。需要进一步研究以确定 CCBRs 的起源和合并异常的确切发生率。建议对 CCBRs 患者进行系统检查，因为已有许多合并异常的报道。
