Background Primary sternal bone tumors are exceedingly rare, with condrosarchomas being among the least common benign lesions. Their proximity to vital mediastinal structures complicates diagnosis and management.
Case Presentation A 31-year-old woman presented with precordial pain and dysphagia. Imaging revealed an expansile lytic lesion with cortical scalloping of the sternal manubrium. Biopsy confirmed chondrosarcoma. En bloc resection of the manubrium was performed, followed by econstruction using a novel «mesh–cement sandwich» technique combining antibiotic-loaded PMMA bone cement with polypropylene mesh and braided polyester sutures. Postoperative recovery was uneventful, with early mobilization, minimal pain, and no complications. Follow-up imaging showed stable reconstruction without recurrence. The patient resumed daily activities pain-free.
Discussion Chondrosarcomas in the sternum can mimic malignancy due to cortical scalloping. Complete resection with tailored reconstruction is essential for symptomatic relief and structural stability. The innovative «mesh–cement sandwich» provides an effective, affordable option, particularly in resource-limited settings.
Conclusion Multidisciplinary surgical planning and the use of antibiotic-loaded cement with mesh enforcement allowed for successful management of a sternal chondrosarcoma, achieving excellent functional and cosmetic outcomes.
