摘要部分“发热”患者只是体表局部温度升高，而体核温度正常，我们将其称之为假热。回顾性分析2013年1月至2020年1月我院发热门诊诊断为“假热”的66例患者的临床资料发现：患者均为青少年，多是感冒症状消失后，腋温不降反而逐渐升高；患者多无明显不适或仅有轻度“头蒙”；实验室检查无明显异常，解热镇痛药退热无效。假热是一种相对独立的临床现象，不属于功能性发热、伪装热，其机制有待研究。

abstractsSome patients who present with a "fever" may only have a localized increase in body surface temperature, while their core body temperature remains normal. This phenomenon is commonly referred to as pseudo fever. A retrospective analysis of clinical data from January 2013 to January 2020 at our fever clinic showed that 66 adolescents were diagnosed with pseudo fever. These patients typically showed a gradual increase in axillary temperature after their cold symptoms had disappeared. Most patients reported no significant complaints other than mild dizziness. Laboratory tests showed no significant abnormalities, and antipyretics were ineffective in lowering their body temperature. Pseudo fever is a relatively independent clinical phenomenon that is distinct from functional fever or simulated fever, and its underlying mechanism remains to be studied.
