Osteosarcoma “tipo osteoblastoma” de columna cervical. A propósito de un caso. [Osteoblastoma like osteosarcoma of the cervical spine]

Abstract

Osteoblastoma-like osteosarcoma; a less aggressive variant of osteosarcoma;is a rare entity and represents 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 located in the cervical spine in a 16-year-old patient. Tomography guided bone biopsy showed a lesion with a permeative growth pattern with suspicion of an osteoblastoma-like osteosarcoma. A total block spondylikectomy was performed through a double approach. We present the clinical case, the diagnostic sequence, the surgical technique and 10-year follow-up.
