Osteogenic sarcoma is the most common primary bone cancer frequently affecting children and teenagers. Despite many years of research, little have the survival rates changed in the last fifty years. Early diagnosis, a complete systemic treatment program with a good tumor response and adequate margins continue to be the main determinants of patients’ prognosis in this disease. Neoadjuvant chemotherapy followed by surgery and subsequent adjuvant systemic treatment remain the standard of care. Numerous reconstruction options available provide these patients better function and improved quality of life.
Se presenta un caso clínico poco frecuente de un quiste óseo aneurismático localizado en el cuboides de un niño de 13 años. Se llegó al diagnóstico mediante la tríada de síntomas, estudios por imágenes (radiografía, resonancia magnética) y anatomía patológica. El tratamiento consistió en el abordaje y curetaje minuciosos dentro de la lesión, el fresado de alta velocidad, la electrocauterización y el relleno con aloinjerto óseo liofilizado con chips cortico-esponjosos. Pese al diagnóstico tardío, la evolución clínica fue favorable con remisión completa de los síntomas y retorno a las actividades deportivas, sin recidiva local.
