丛状神经纤维瘤

【疾病难度】★★★

【疾病编码】9550/0

【疾病定义】

  • 是一种良性的周围神经鞘膜肿瘤,是神经纤维瘤的一种组织学亚型。由施万细胞、神经束膜样细胞、成纤维细胞、肥大细胞和残留的有髓或无髓神经以及成纤维细胞组成

【临床特征】

  • 40%的病例伴有1型神经纤维瘤病(NF1)

  • 多发生于青年人

  • 可发生于浅表或深部组织

【大体特征】

  • 结节状和或蠕虫状外观,切面均匀棕褐色/灰褐色,有光泽,黏液样,呈半透明和实性肿瘤

【镜下特征】

  • 结构:呈结节状(蠕虫状),缺之包膜,易浸润下面的软组织和母体神经;

  • 细胞形态:具有细而波浪状核的温和的梭形细胞;

  • 细胞组成:由施万细胞、神经束膜样细胞、成纤维细胞、肥大细胞和残留的有髓或无髓神经以及成纤维细胞组成

  • 背景:为黏液样、胶原性(胡萝卜丝)的间质

【免疫组化】

  • 肿瘤细胞S100,SOX10(+)+间质细胞CD34(+)+残存的轴突NF(+)+散在的神经束膜细胞EMA(+)

【诊断公式】

  • 丛状神经纤维瘤=大体表现(结节状)+波浪状的核+黏液样、胶原性(胡萝卜丝)的间质+免疫组化

【鉴别诊断】

  • 神经鞘瘤

  • 隆突性皮肤纤维肉瘤

  • 神经束膜瘤

【讨论鉴析】

  • 丛状神经纤维瘤是NF1的特征性表现,考试时常会出现牛奶咖啡斑
