摘要
通过对1例儿童膝关节旁纤维性错构瘤的组织病理及临床表现进行观察，并复习相关文献。最终依靠病理结果确定本例为膝关节旁软组织内罕见的错构瘤。组织学上，肿瘤由束状排列的长梭形细胞、幼稚的未分化间叶细胞和成熟的脂肪组织不同比例组成。免疫组织化学上，幼稚的间叶细胞表达CD34，而梭形细胞表达平滑肌肌动蛋白(smooth muscle actin，SMA)。儿童膝关节旁纤维性错构瘤是一种罕见的原发性软组织良性病变，发病缓慢，容易误诊，通过完整切除肿瘤，预后良好。

Abstract
The clinical data of 1 case with knee mass in a child were observed. The final diagnosis was fibrous hamartoma around the knee and confirmed by pathology .In histology, the tumor is composed of a different proportion of long fusiform cells, immature mesotype and mature adipose tissue. In immunisation, immature mesenchymal cells expressed CD34 and the spindle cells expressed smooth muscle actin (SMA). The fibrous hamartoma of children in knees is a rare benign tumor derived from the soft tissues and easy to be misdiagnosed. Because of the slowing onset and easily complete resection, the prognosis of this tumor is good.
