It is typically described in adults between 40 and 70 years of age, being the majority of the series published in this age group. The objective of this study was to report a series of young adults (16-40 years old) with a diagnosis of chondrosarcoma of bone in order to describe the particularities of this tumor in this population. From a total of 37 patients between 16 and 40 years old, surgically treated for chondrosarcoma in our institution, 18 had low-grade tumors (G1/atypical cartilaginous tumor), 16 had an intermediate-grade (G2), and a minority had high-grade tumors (2 with a G3 and 1 with a dedifferentiated chondrosarcoma). The overall survival rate was 97% (95% CI 82%-99%) at 2 years of follow-up and 90.5% (95% CI 73-96) at 5 years of follow-up. The local recurrence free rate was 92% (95% CI % 77%-97.5%) at 1 year of follow-up and 89% at 2 and 5 years of follow-up (95% CI 73%-96%). Histological grade was the most relevant prognostic factor. The concordance of the histological grade between the preoperative diagnosis of the biopsy and the surgical resection material was 81% (30/37). Publisher: El condrosarcoma ocupa el segundo lugar en frecuencia, entre los tumores malignos primarios óseos, en pacientes adultos. Típicamente afecta a adultos de entre 40 y 70 años, siendo la mayoría de las series publicadas de este grupo etario. El objetivo de este estudio fue comunicar una serie de pacientes adultos jóvenes (16 a 40 años) con diagnóstico de condrosarcoma óseo, que buscó describir las particularidades en la forma de presentación en esta población. De un total de 37 pacientes de 16 a 40 años operados por condrosarcoma en nuestro centro, entre los años 2008 y 2019, 18 presentaron tumores de bajo grado (G1/tumor cartilaginoso atípico), 16 de grado intermedio (G2), quedando una minoría con tumores de alto grado (2 con condrosarcoma G3 y 1 con un condrosarcoma desdiferenciado). La tasa de supervivencia global fue del 97% (IC 95% 82%-99%) a 2 años y 90.5% (IC 95% 73%-96%) a 5 años y la tasa libre de recurrencia local fue de 92% (IC 95% 77%-97.5%) a los 12 meses y de 89% a los 2 y 5 años (IC 95% 73%-96%). El grado histológico fue el factor pronóstico más relevante. La concordancia del grado histológico entre el diagnóstico preoperatorio de la biopsia y el material de resección quirúrgica fue del 81% (30/37).
