Abstract

Choroid plexus tumors are neuroepithelium-derived tumors arising in the ventricles of the central nervous system. They are commonly seen in childhood and correspond to low rates in all central nervous system tumors. Due to their rareness and similar histomorphologic features to other tumors, their diagnosis might be challenging. Here, we used the OTX-2 antibody to evaluate the diagnostic role of OTX-2 expression in choroid plexus tumors. We performed a retrospective review of 34 patients operated for choroid plexus tumors in our center between 2011 and 2023. Additionally, as different tumor types are also arising in the ventricles, we selected five cases each of AT/RT, germ cell tumor, ependymoma, and metastatic adenocarcinoma from the pathology archive. Immunohistochemistry conditions were adjusted for each specific antibody based on the manufacturers' recommendations for concentrations and antigen retrieval/blocking. OTX-2, S-100, and transthyretin antibody staining was performed on sections from each case.

OTX-2表达作为脉络膜丛肿瘤的诊断标志物。
脉络膜丛肿瘤是发生在中枢神经系统脑室的神经上皮源性肿瘤。它们常见于儿童,在所有中枢神经系统肿瘤中发病率较低。由于其罕见性和与其他肿瘤相似的组织形态学特征,其诊断可能具有挑战性。在这里,我们使用OTX-2抗体评估OTX-2表达在脉络膜丛肿瘤中的诊断作用。我们对2011年至2023年间在本中心接受脉络膜丛肿瘤手术的34例患者进行了回顾性分析。此外,由于脑室也出现不同类型的肿瘤,我们从病理档案中选择了AT/RT、生殖细胞瘤、室管膜瘤和转移性腺癌各5例。根据制造商推荐的浓度和抗原回收/阻断,对每种特异性抗体的免疫组织化学条件进行调整。对每个病例的切片进行OTX-2、S-100和转甲状腺素抗体染色。
