Hemangiopericytoma (HPC) may develop in every site where the endothelial tissue exits and primarily develops in the skeletalmuscular system or the skin. Adult cases of HPC generally exhibit a benign course. 20-30% of the cases may show a malign course. The tumors that show more than four mitoses, a focal area of necrosis, and increased cellularity on a magnification x10 are considered as malign. In our paper, we presented our case who showed a lung metastasis at the end of 4 years and who developed a pathological fracture of the right humerus at the end of approximately 2 years, because hemangiopericytoma is rarely seen in the chest wall as a primary tumor.
