Objective: To investigate the histological type and clinicopathological characteristics of the craniocerebral slope tumors with chondromucinous features. Methods: Retrospective analysis was conducted to analyze chondromucinous tumors in the slope area diagnosed at Henan Provincial People's Hospital from October 2011 to June 2018. Relevant clinical and pathological data were reviewed, and immunohistochemistry was used to investigate the immunophenotype of the tumors. Results: Eight cases were identified, including 4 males and 4 females with patient age ranging from 20 to 48 years. Histologically, there were 1 case of chordoid meningioma, 1 chondromyxoid fibroma, 1 mucinous chondrosarcoma, 1 Maffucci syndrome, and 4 chondroid chordomas. Conclusion: Chondromucinous tumors of the slope area include chordoma, chordoid meningioma, chondromyxoid fibroma, and myxoid chondrosarcoma and their correct diagnosis is mainly based on the morphological characteristics, immunophenotype and comprehensive analysis of clinical data.
目的： 探讨颅脑斜坡区具有软骨黏液样特征肿瘤的组织学类型、临床病理学特征。 方法： 回顾性收集并分析2011年10月至2018年6月河南省人民医院诊断的斜坡区具有软骨黏液样特征肿瘤，复查相关临床及病理资料，同时采用免疫组织化学法检测相应肿瘤的免疫表型。 结果： 斜坡区具有软骨黏液样特征肿瘤共8例，男性4例，女性4例，年龄范围20~48岁，脊索样脑膜瘤1例，软骨黏液样纤维瘤1例，黏液样软骨肉瘤1例，马弗西（Maffucci）综合征患者软骨瘤1例，软骨样脊索瘤4例。 结论： 斜坡区脊索瘤、脊索样脑膜瘤、软骨黏液样纤维瘤、软骨瘤、黏液样软骨肉瘤可具有软骨黏液样特征，其鉴别诊断主要依据形态学特征、免疫表型及临床资料综合分析。.
