[Therapeutic choice in primary costal tumors]

Primary rib tumors constitute a rare entity and have only seldom been studied separately. In a retrospective study based on 21 cases, with the help of the literature, we try to specify the specific problems encountered with rib tumors and the therapeutic consequences that follow. Our series comprises 10 benign tumors, 3 malignant tumors and 8 cartilaginous tumors. The benign tumors were resected and all the patients recovered uneventfully. One of the patients died of a plasmocytoma 92 months after resection. Among the cartilaginous tumors, we observed two recurrences after 9 and 24 months from which the patient died eventually at 20 and 72 months after resection. The histologic diagnosis of a rib tumor must be made through an excisional biopsy. Cartilaginous tumors are potentially malignant. They must be treated as malignant tumors by radical resection and primary reconstruction. The long-term follow-up of every patient carrying a rib tumor is mandatory because of the risk of late recurrence.
