Background

This study aimed to clarify the relationship between primary site and lymphatic drainage pattern for malignant skin tumors in the head and neck region. Malignant melanoma and squamous cell carcinoma in the head and neck region are known to have poor prognosis because of lymph node metastasis. Nevertheless, numerous aspects of lymphatic drainage patterns remain elusive.

Methods

We statistically analyzed data of 47 patients with malignant skin tumors in the head and neck region. Information was collected on the patients' clinical characteristics, primary tumor site, and lymphatic drainage patterns.

Results

The parotid lymph nodes drained the greatest amount of lymph from skin tumors of the head and neck. Important lymphatic drainage pathways were the superficial cervical nodes for primary tumors in the buccal/nasal region, level IA and level IB nodes for primary tumors in the lip region, the occipital nodes, posterior auricular nodes, and level VA nodes in the parietal/occipital region, and the preauricular nodes in the auricular region.

Conclusion

These findings have considerable significance in terms of understanding lymphatic drainage patterns for malignant skin tumors in the head and neck and may be useful for clinical decision-making and when planning treatment. Further research and clinical applications are expected to contribute to an improved prognosis in patients with cutaneous head and neck malignancies.

头颈部恶性皮肤肿瘤的淋巴引流模式：单中心回顾性研究

背景

本研究旨在阐明头颈部恶性皮肤肿瘤的原发部位与淋巴引流模式的关系。头颈部恶性黑色素瘤和鳞状细胞癌因淋巴结转移而预后不良。然而，淋巴引流模式的许多方面仍然难以捉摸。

方法

我们对47例头颈部恶性皮肤肿瘤患者的数据进行了统计分析。收集患者的临床特征、原发肿瘤部位和淋巴引流模式的信息。

结果

腮腺淋巴结排出头颈部皮肤肿瘤的最大量的淋巴液。重要的淋巴引流途径是颊/鼻区原发肿瘤的颈浅淋巴结、唇区原发肿瘤的IA级和IB级淋巴结、顶叶/枕叶的枕叶淋巴结、耳后淋巴结和VA级淋巴结。区，以及耳区的耳前结节。

结论

这些发现对于了解头颈部恶性皮肤肿瘤的淋巴引流模式具有相当大的意义，并且可能有助于临床决策和规划治疗。进一步的研究和临床应用预计将有助于改善头颈部皮肤恶性肿瘤患者的预后。
