副肿瘤性自身免疫性脑炎(PAE)是一组与肿瘤疾病相关的罕见神经综合征。在这里,我们报告了一个病例,在PAE患者中存在多种抗神经元抗体,他同时发展为小细胞肺癌和结直肠腺癌。此外,结直肠腺癌的免疫病理检查显示,肿瘤组织中有异常神经元抗原的形成和大量浆细胞的浸润。这些发现支持这样的假设,即肿瘤中神经元抗原的表达启动了PAE的自身免疫反应。
Paraneoplastic autoimmune encephalitis (PAE) represents a group of rare neurological syndromes associated with neoplastic diseases. Here, we report a case that multiple anti‐neuronal antibodies were present in a patient with PAE who developed both small cell lung cancer and colorectal adenocarcinoma. Furthermore, the immunopathological investigation of the colorectal adenocarcinoma revealed the formation of abnormal neuronal antigens and a massive infiltration of plasma cells in the tumor tissue. These findings support the hypothesis that expression of neuronal antigens in neoplasm initiates autoimmune responses in PAE.
