鼻腔鼻窦非肠型腺癌远处腮腺转移1例

Distant Parotid Metastasis of Non-intestinal Adenocarcinoma of the Nasal Cavity and Sinuses: A Case Report

摘要:

鼻腔鼻窦非肠型腺癌(Non-intestinal adenocarcinoma of the nasal cavity and paranasal sinuses ，non-ITAC)是一种少见恶性肿瘤，其远处转移模式尚未明确，腮腺转移极为罕见。本文报道1例鼻腔鼻窦非肠型腺癌远处腮腺转移的临床资料，并进行相关文献复习。总结患者临床表现、影像学特征、病理及免疫组化结果、治疗方案及随访情况。为复发/转移性non-ITAC患者提供新的治疗思路。

Abstract:

Non-intestinal adenocarcinoma of the nasal cavity and paranasal sinuses (non-ITAC) is a rare malignant tumor whose pattern of distant metastasis remains unclear, with parotid gland metastasis being exceptionally rare. This article reports a clinical case of non-ITAC with distant metastasis to the parotid gland, along with a review of relevant literature. The patient''s clinical presentation, imaging characteristics, pathological and immunohistochemical findings, treatment strategies, and follow-up outcomes are summarized. This case provides new insights for the management of recurrent or metastatic non-ITAC patients.
