软组织肿瘤是一种常见疾病,可以发生在初生到老年的任何年龄。软组织肿瘤起源于粘液、纤维、脂肪、平滑肌、横纹肌、间皮、滑膜、血管、淋巴等间叶组织,并位于软组织部位(内脏器官除外)。临床上,软组织肿瘤还包括来自周围神经系统的肿瘤。尚有一些发生于软组织内,虽然细胞起源不明,但可能来源于间叶组织的,也包括在软组织肿瘤内。 由于间叶干细胞可向多种类型的组织分化,所以软组织肿瘤的类型也很多,表1各种类型中又可分为良性肿瘤、瘤样病变和恶性肿 Soft tissue tumors are a common disease that can occur at any age from newborn to old age. Soft tissue tumors originate in mucous, fibrous, adipose, smooth muscle, striated muscle, mesothelial, synovial, vascular, and lymphatic mesenchymal tissues, and are located in soft tissues (except visceral organs). Clinically, soft tissue tumors also include tumors from the peripheral nervous system. Some of these occur in soft tissues. Although the origin of the cells is unknown, they may be derived from mesenchymal tissue and also include soft tissue tumors. Because the mesenchymal stem cells can differentiate into various types of tissues, there are many types of soft tissue tumors. Table 1 can be divided into benign tumors, tumor-like lesions, and malignant tumors in various types.
