Recurrent parachordoma of the lower back: A case report.

Parachordoma is a rare entity with less than 50 cases described in the literature. This soft-tissue tumor resembles chordomas as well as extraskeletal myxoid chondrosarcomas and has only recently been fully characterized. Here we describe the case of a patient with a lower back parachordoma and its subsequent postresection recurrence 9 years after the initial procedure, emphasizing the importance of long-term follow-up in individuals with this diagnosis.
