Small cell osteosarcoma is rare, representing 1-4% of all osteosarcomas. We experienced a case of small cell osteosarcoma in an 8-year-old girl on her calcaneus. Histologically, the tumor consists of small round cells that resemble those of Ewing's sarcoma, and variable foci of lacy osteoid formation between tumor cells. The rare location, histologic characteristics and differential diagnostic points are discussed.
小细胞骨肉瘤很罕见，占所有骨肉瘤的1%-4%。我们遇到一例发生于一名8岁女孩跟骨的小细胞骨肉瘤。组织学上，肿瘤由类似尤文肉瘤的小圆形细胞组成，肿瘤细胞之间有不同程度的花边状骨样组织形成灶。本文讨论了该罕见部位、组织学特征及鉴别诊断要点。
