To our knowledge, this is the first case report of CT and MRI evidence of a low-grade iliac chondrosarcoma in a patient under the age of 5 years.

据我们所知，这是第一个包含电脑断层摄影及磁振造影像，讨论五岁以下病患低度软骨肉瘤的病例报告。

With the application of CT-guided biopsy, the accurate rate of pathologic examination and the rate of pathologic diagnosis of chondrosarcoma before operation are improved.

CT引导下软骨瘤穿刺活检，提高了病理学检查取材的准确性和软骨肉瘤的术前病理诊断率。

RESULTS: We detected immunohistochemical evidence of type II collagen within both the extracellular matrix-rich and matrix-poor areas in all 15 cases of clear cell chondrosarcoma.

结果：在15例透明细胞软骨肉瘤的细胞外基质富集区和基质贫乏区，都发现了II型胶原的免疫组化证据。

Materials and Methods:The plain film and CT features of pelvic chondrosarcoma in 20 surgically and pathologically proved cases, including 7 recurrent cases, were reviewed.

材料与方法：分析总结经手术及病理证实的20例骨盆部软骨肉瘤的平片及CT表现(包括7例复发)。

The calcification varies in appearance but can be stippled and amorphous, not unlike the chondroid calcifications seen with extracranial chondrosarcomas.

钙化表现是多样的，可以是斑点状或不定形的，不太类似颅外的软骨肉瘤的软骨钙化。

Staining extent and intensity were evaluated semiquantitatively and mean values for each parameter were calculated. Immunostaining with D2-40 showed positivity in 100% of skeletal myxoid chondrosarcomas, 96% of enchondromas, 95% of low-grade chondrosarcomas, 80% of chordoid meningiomas, and 75% of chordoid gliomas. Staining with S100 demonstrated diffuse, strong positivity in all (100%) chordoid gliomas, skeletal myxoid chondrosarcomas, low-grade chondrosarcomas, and enchondromas, 94% of chordomas, and 81% of extraskeletal myxoid chondrosarcomas, with focal, moderate staining in 40% of chordoid meningiomas.

我们半定量地评估了这些免疫染色的广度和强度，并且计算了它们各自的平均值。D2-40阳性表达于100%例骨的黏液样软骨肉瘤、96%例内生性软骨瘤、95%例低级别软骨肉瘤、80%例脊索样脑膜瘤和75%例脊索样胶质瘤。S100染色弥漫且强烈地表达于所有的（100%）脊索样胶质瘤、骨的黏液样软骨肉瘤、低级别软骨肉瘤和内生性软骨瘤，94%例脊索瘤，81%例骨外黏液样软骨肉瘤，还有，局灶性、中度表达于40%例黏液样脑膜瘤。

In this study, immunohistochemical staining was performed with antibodies against D2-40, S100, pankeratin, epithelial membrane antigen, brachyury, and glial fibrillary acidic protein in 4 cases of chordoid glioma, 6 skeletal myxoid chondrosarcomas, 10 chordoid meningiomas, 16 extraskeletal myxoid chondrosarcoma, 18 chordomas, 22 low-grade chondrosarcomas, and 27 enchondromas.

本研究中，我们给4例脊索样胶质瘤、6例骨的黏液样软骨肉瘤、10脊索样脑膜瘤、16例骨外黏液样软骨肉瘤、18例脊索瘤、22例低级别软骨肉瘤和27例内生性软骨瘤做了D2-40、S100、pankeratin、上皮膜抗原、brachyury和胶质纤维酸性蛋白的免疫组化染色。
