Non-epithelial tumors of the nasal cavity, paranasal sinuses, and nasopharynx: A clinicopathologic study(III. Cartilaginous tumors (chondroma, chondrosarcoma))

In a review of non-epithelial tumors involving the nasal cavity, paranasal sinuses, and nasopharynx, 256 lesions, 156 benign and 100 malignant, were identified. of these, 17 were cartilaginous neoplasms, 7 chondromas and 10 chondrosarcomas. The clinical findings associated with these cartilaginous tumors are described, the histologic features illustrated, results of therapy presented, and clinicopathologic correlations made. Chondromas were small asymptomatic incidentally found nodules which were successfully treated by limited local resections. The prognosis of the chondrosarcomas depended upon: 1) the location and extent of the lesion; 2) the adequacy of the surgical therapy; and 3) the degree of differentiation of the tumor.
