Primary tumours of the sternum

In 1966-1986, two men and four women (mean age 47.5 years) underwent surgery for primary sternal tumour. Three of the tumours were benign (two condromata, one osteochondroma) and three were malignant (two chrondrosarcomata, one reticulum cell sarcoma). Inflammatory or degenerative lesions impeded differential diagnosis in three additional cases (without tumour). The tumours were treated with radical resection of the affected part of the sternum, including the relevant attached structures. Marlex-mesh reconstruction of the defect was necessary in four cases. There was no operative mortality. One Marlex graft became infected. At follow-up (average 11.1 years, range 9.0-14.7 years), five patients were alive without recurrence of tumour and the sixth had died of unrelated cause.
