Condrosarcoma toracoabdominal: Resección quirúrgica de cinco arcos costales, reconstrucción de pared torácica con osteosíntesis y frenorrafia

Introduction. Chondrosarcoma is the most common primary malignant tumor of the chest wall, with a low incidence and a predilection for the ribs. It is typically diagnosed in young adults, and its behavior varies according to histological grade. Clinical case. A 32-year-old male patient with a three-month history of right-sided abdominal pain underwent a percutaneous biopsy, which confirmed a diagnosis of chondrosarcoma. He underwent surgery via a combined thoracoabdominal approach involving en bloc resection of the mass, including the sixth through tenth ribs, the diaphragm, and the peritoneum. Reconstruction was performed using synthetic mesh, phrenorrhaphy, and costal osteosynthesis. Results. The patient showed a favorable clinical course and was discharged on the sixth postoperative day. Histopathological examination confirmed a grade I chondrosarcoma with negative surgical margins. During outpatient follow-up, the patient remains free of ventilatory compromise or chest wall deformity. Conclusions. This case illustrates the importance of a multidisciplinary approach and detailed surgical planning in the management of costal chondrosarcoma. Complete resection with appropriate chest wall reconstruction preserves ventilatory mechanics, reduces respiratory complications, and leads to better functional recovery.
