Abstract：Objective To study clinicopathologic features, diagnosis and differential diagnosis of recurrent chondromyxoid fibroma and its pseudosarcoma-like change.Methods Recurrent chondromyxoid fibroma and its pseudosarcoma-like change in 2 cases was analyzed and related literature was reviewed.Results There were 2 male cases involved ( case 1: 13 years old; case 2: 9 years old ). Recurrence occurred in case 1 of chondromyxoid ifbroma in the first metatarsal of the left foot 18 months postoperatively. Recurrence occurred in case 2 of chondromyxoid fibroma in the femur 30 months postoperatively. Histological pathology showed both chondromyxoid fibroma and pseudosarcoma-like features. Immunohistochemical study showed that the Vimentin and S-100 were positive. Conclusions Chondromyxoid ifbroma is a rare and benign tumor. Pseudosarcoma-like features can be found after recurrence. Diagnosis should be made combining clinical data, pathological and histological manifestations. It should be differentiated from other bone malignant tumors.
