Two hundred fifty-six non-epithelial tumors of the nasal cavity, paranasal sinuses, and nasopharynx have been identified in the records of this department; 156 were benign and 100 malignant. The histologic classification and distribution of these lesions are presented. Vascular neoplasms were the most common, with 85 of the 256 cases being found in this category. The clinical findings related to the vascular tumors are discussed and their histologic features presented. Results of treatment are reviewed, and clinicopathologic correlations are made.
