SUMMARY

This case report presents the case of a 68-year-old man, who presented with slow-growing, slightly painful infiltration in the lower half of the sternum observed for two years. According to the performed computed tomography examination, a 7 * 6 * 6.5 cm infiltration of the middle part of the sternum was found. Lesion was extending 1 cm ventrally and 4 cm dorsally into the surrounding soft tissues. An open biopsy was performed with the finding of moderately differentiated (grade 2) conventional chondrosarcoma. Subsequently a multidisciplinary team composed of: the Musculoskeletal tumour committee of the Masaryk Oncology Institute in Brno, the 1^st Orthopaedic Clinic of St. Anne's Faculty Hospital in Brno and the 1^st Surgical Clinic of St. Anne's Faculty Hospital in Brno had referred the patient to plan and perform the surgical resection of the tumours lesion. A partial resection of the sternum with the tumor was performed, followed by reconstruction of the defect with two condensed polytetrafluoroethylene meshes using the so called „sandwich technique". Then the defect was strengthened using titanium splints and subsequently reconstructed by pectoralis major muscle flap. Definitive histology confirmed the finding of grade 2 conventional sternal chondrosarcoma.
