Chordoma of the Lower Back in an Adolescent: A Rare Cytologic Presentation

Abstract

Chordomas are low-grade malignant tumors of bone that occur almost exclusively in the axial skeleton. Chordomas are rare in children and adolescents and comprise <5% of all cases and the site of development is at the skull base. These tumors are believed to behave more aggressively than chordomas in adults and may have unusual morphology. We herein present a rare case of chordoma in a 20-year-old male with low back mass, diagnosed on fine needle aspiration cytology.
