A case of infantile fibrosarcoma on the back was reported. A three-year-old girl was noticed to have a tumor on her back one year ago. She had not received the treatment for a year because she had no symptom and the size of the tumor remained unchanged. She underwent local excision of solid tumor, which was 2cm in diameter and which invaded the muscular layer. Microscopically, it was composed of spindle-shaped tumor cells with high cellularity, and infiltration of chronic inflammatory cells and hemangiopericytoma like tissue in some part. The diagnosis was an infantile fibrosarcoma. She has received no ajuvant therapy and has been well without recurrence for 5 months postoperatively. we have collected 28 cases of infantile fibrosarcoma reported in Japanase literatures. Characteristically, the tumors were noticed before 3 months of age in 25 cases and the average size was 6.8cm at operation. And local recurrence was occured in 4 cases, but no metastasis have been reported.
