采用多学科的方法来表征软组织肿瘤。在抽吸材料制备的涂片中,发现均匀的肿瘤细胞,嵌入粘液基质中,部分排列成花边状。组织病理学显示透明质酸酶稳定黏蛋白基质中的细胞呈花边状。在一些肿瘤细胞中发现了S - 100蛋白的细胞质阳性。电镜分析显示内胆有微管聚集。所有这些特征都符合骨外黏液样软骨肉瘤(EMC)的诊断。DNA流式细胞术显示二倍体DNA含量。细胞遗传学检查显示肿瘤核型为45、XY、t(2;11)(q31;p15)、t(9;22)(q22.3;q12)、dic(13;22)(p11;p13)。因为相似的9;22‐易位在另外两个EMC病例中也有描述,我们得出结论,t(9;22)(q22-31; q11-12)是这种肿瘤类型的特异性重排。因此,细胞遗传学分析可能在检查具有这种和类似组织学的肿瘤时具有诊断价值。
A multidisciplinary approach was taken to characterize a soft tissue tumour. In smears prepared from aspirated material, uniform tumour cells, embedded in a myxoid matrix and partly arranged in a lace‐like pattern, were found. Histopathology showed a lace‐like pattern of cells in a matrix of hyaluronidase‐stable mucins. Cytoplasmic positivity for S‐100 protein was found in some tumour cells. Electron microscopic analysis revealed intracisternal aggregates of microtubules. All these features are consistent with the diagnosis of extraskeletal myxoid chondrosarcoma (EMC). DNA flow cytometry showed a diploid DNA content. Cytogenetic examination revealed the tumour karyotype 45, XY, t(2;11)(q31;p15), t(9;22)(q22.3;q12), dic(13;22)(p11;p13). Because similar 9;22‐translocations have been described in two other cases of EMC, we conclude that t(9;22)(q22–31;q11–12) is a specific rearrangement in this tumour type. Cytogenetic analysis may thus be of diagnostic value in the examination of tumours with this and similar histologies.
