Osteosarcoma "tipo osteoblastoma" de columna cervical: A propósito de un caso. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2019, vol.84, n.2, pp.149-154. ISSN 1852-7434.

Osteoblastoma-like osteosarcoma, a less aggressive variant of osteosarcoma, is a rare tumor which presents a clinical and histopathological diagnostic challenge. We have found few reports of cases of this tumor in the literature. In this case, we describe an osteoblastoma-like osteosarcoma of the cervical spine in a 16-year-old patient. CT-guided bone biopsy showed a lesion with a permeated growth pattern, which led to the suspicion of an osteoblastoma-like osteosarcoma. A total en bloc spondylectomy was performed through a dual approach. We present the clinical case, the diagnostic sequence, the surgical technique and 10-year follow-up results.

Keywords : Osteoblastoma-like osteosarcoma; Aggressive osteoblastoma; Spondylectomy; Tumor; Cervical spine.
