An oral burning sensation with unidentified cause in patients with preexisting psychosocial conditions is usually diagnosed as burning mouth syndrome. However, unexpected organic lesions may be detected in rare cases. A 35-year-old woman had chief complaints of a burning sensation and numbness of the right side of the lip and tongue, as well as a dry sensation of the mouth with a taste disturbance of the right side of the tongue. The symptoms were continuous and did not show any daily fluctuations. The symptoms started without any recognizable triggering factor six months before her first visit to our clinic,. No abnormality was detected in her mouth. MRI images revealed an approximately 30 × 30 mm well-defined mass localized in the right cerebropontine angle compressing the trigeminal nerve, which was diagnosed as schwannoma of the right auditory nerve. It is important for clinicians to consider the possibility of brain tumors in their differential diagnosis of BMS. Although it is not always easy to eliminate all diseases that may cause an oral burning sensation in patients with BMS-like symptoms, more attention and careful examination based on the patient’s psychosomatic background features and other possible causes are needed to rule out organic diseases.

模仿灼口综合征的前庭神经鞘瘤1例

患有先天性社会心理状况的患者因口灼烧感不明原因通常被诊断为口灼灼综合症。但是，在极少数情况下可能会发现意外的器质性病变。一名35岁的女性主诉嘴唇和舌头右侧有灼热感和麻木感，以及舌头右侧有味觉障碍的口干感。症状是连续的，没有任何日常波动。在她第一次去我们的诊所前六个月，症状开始时没有任何可识别的触发因素。在她的嘴中未发现异常。MRI图像显示约30×30 mm的明确肿块位于右脑桥角压迫三叉神经，被诊断为右听神经鞘膜瘤。对于临床医生而言，在BMS的鉴别诊断中考虑脑肿瘤的可能性非常重要。尽管并非总是容易消除所有可能引起BMS样症状患者口腔灼热感的疾病，但需要根据患者的心身背景特征和其他可能的原因进行更多的关注和仔细检查，以排除器质性疾病。
