由于软组织肿瘤的发病率较低，类型繁多且复杂，不同类型的软组织肿瘤之间在组织学上存在较大的重叠性，又有很多假肉瘤样病变和中间性肿瘤的存在，使得软组织肿瘤的病理诊断一直成为外科病理领域中的难点。要提高软组织肿瘤的诊断水平，不仅需要对软组织肿瘤的病理有一个比较全面的了解，熟悉一些常用的辅助性检测手段，而且要注重临床、影像和病理三者相结合。此外，坚持阅读文献，关注新进展，了解新病种，对拓展视野也很重要。

Abstract    Owing to the low incidence, complexity in histological appearance, overlapping features between different entities, lots of pseudosarcomatous lesions and tumors of intermediate malignancy, the diagnosis of soft tissue tumors is one of most challenging job in surgical pathology. It is recommended that pathologists should not only rely on the histology alone. The correlations between clinic, radiology and pathology are essential in arriving at the correct diagnosis. Moreover, regular screening of the recent literatures with focus on the advancement of soft tissue tumors and newly described entities are also very important.
