Late relapsing parosteal osteosarcoma has been reported very rarely;however, to the best of our knowledge, long-term repeated recurrence of this tumor has not been reported yet. Herein, we present a case of late relapsing low grade parosteal osteosarcoma after 15 years in popliteal cavity after advising tumor excision, removal of the organ involved, and the placement of prosthesis.
