Numb chin syndrome (NCS) refers to a rare sensory neuropathy characterized by numbness of the chin within the distribution of the mental or inferior alveolar nerve. Although NCS is usually caused by a benign process, it should not be underestimated and a thorough diagnostic evaluation for a new or known progressive malignancy should always be performed. Here, we report a case of salivary ductal adenocarcinoma that mimicked a pulpitis and periodontitis in its early presentation accompanied by numbness of chin. The course and diagnosis of this case are discussed, and a brief review of the literature is presented. It is hoped for clinicians to keep the malignant possibility of NCS in mind and take a thorough examination.
麻木性颏综合征（NCS）是一种罕见的感觉神经病变，其特征为颏部在颏神经或下牙槽神经分布区域内出现麻木。尽管NCS通常由良性病变引起，但不应被低估，对于新发或已知的进行性恶性肿瘤应始终进行全面的诊断评估。在此，我们报告一例涎腺导管腺癌病例，该病例在早期表现为类似牙髓炎和牙周炎，并伴有颏部麻木。本文讨论了该病例的病程及诊断，并对相关文献进行了简要综述。希望临床医生牢记NCS的恶性可能性并进行全面检查。
