The term "chameleon" was first used in the seventeenth century by Sydenham to describe a patient with a protean semiology. We report a single case of "chameleon" syndrome that challenges the current international criteria for somatoform disorders, dissociative amnesia, and Ganser syndrome. The florid symptoms were as follows: anterograde and retrograde amnesia (including semantic, episodic, and procedural deficits), loss of identity, atypical neuropsychological impairment (approximate answers), left sensitive and motor deficit, and left pseudochoreoathetosis movement disorders. Additional behavioral disorders included the following: anxiety, clouded consciousness, hallucinations, and "belle indifference". A single photon emission computed tomography examination showed bilateral temporal, frontal and a right caudate (in the head of the caudate nucleus) hypoperfusion concordant with a common mechanism of repression in these disorders.
“变色龙”一词最早在17世纪由西德纳姆用来描述具有多变症状学的患者。我们报告一例“变色龙”综合征病例，该病例对当前国际上关于躯体形式障碍、分离性遗忘症和甘塞尔综合征的标准提出了挑战。其明显症状如下：顺行性和逆行性遗忘（包括语义、情景和程序性缺陷）、身份丧失、非典型神经心理学损害（近似回答）、左侧感觉和运动缺陷以及左侧假手足徐动症运动障碍。其他行为障碍包括：焦虑、意识模糊、幻觉和“泰然漠视”。单光子发射计算机断层扫描检查显示双侧颞叶、额叶以及右侧尾状核（尾状核头部）灌注不足，这与这些障碍中常见的压抑机制相一致。
