RESUMEN
Osteochondroma or osteocartolaginous exostosis is by far the most common benign bone tumour, which accounts for 35% to 50% of benign bone neoplasms and 10% to 15% of all primary bone tumours. Osteochondroma represents a developmental enchondromatous hyperplasia which leads to formation of cartilage capped bony protrusions on bony surfaces. We present a case report of a 14-year- old female, who presented to us with a hard, gradually progressing, large painless swelling, over the left side of her neck. Swelling was nontender, extending from dorsal to ventral aspect, measuring 6 x 8 cm. Therefore, we are interested in introducing our case to medical fraternity, in which a giant lower cervical spine osteochondroma was seen in an adolescent female patient.
