Resumen


El osteosarcoma “tipo osteoblastoma”, una variante menos agresiva del osteosarcoma, es una enfermedad poco frecuente y representa un desafío diagnóstico tanto clínico como histopatológico. Se han publicado escasos reportes de casos de este tumor.
Presentamos a un paciente de 16 años con un osteosarcoma “tipo osteoblastoma” localizado en la columna cervical. La biopsia ósea bajo tomografía reveló una lesión con un patrón de crecimiento permeativo, con sospecha de osteosarcoma “tipo osteoblastoma”. Se realizó una espondilectomía total en bloque mediante un doble abordaje. Se describen el caso clínico, la secuencia diagnóstica, la técnica quirúrgica y el seguimiento a 10 años.

 

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.


Palabras clave
