软组织透明细胞肉瘤(clear cell sarcoma of softtissues,CCS)是一种患病率较低的软组织肿瘤,占软组织肉瘤的1%。WHO(2002)软组织肿瘤分类将其归类于分化不确定的肿瘤,因其肿瘤细胞具有黑色素细胞分化特点,将其归入恶性黑色瘤中的一种亚型。CCS的部分病例HE染色可见黑色素颗粒,也有文献称其为软组织恶性黑色素瘤(malignant melanoma of soft parts,MMSP)[1]。由于CCS临床表现多无特异性,易导致误诊、误治,为提高对其的认识,本文收集6例CCS临床病理资料,并结合有关
Clear cell sarcoma of soft tissue (CCS) is a kind of soft tissue tumor with low prevalence, accounting for 1% of soft tissue sarcoma. The classification of soft tissue tumors by the WHO (2002) classified them as tumors of indeterminate differentiation. Because the tumor cells have the characteristics of melanocyte differentiation, they are classified as a subtype of malignant melanoma. In some cases of CCS, melanin granules can be seen by HE staining, and there are also known in the literature as malignant melanoma of soft parts (MMSP) [1]. Because the clinical manifestations of CCS are more non-specific and easily lead to misdiagnosis and mistreatment, in order to improve the understanding of CCS, the clinical pathological data of 6 cases of CCS were collected and combined with relevant information.
