Non-epithelial tumors of the nasal cavity, paranasal sinuses and nasopharynx: a clinico-pathologic study. VII. Myxomas.

In a study of non-epithelial tumors involving the nasal cavity, paranasal sinuses and nasopharynx, 256 lesions, 156 benign and 100 malignant, were identified. Of these, six were classified as myxoma. Myxomas of facial bones, neoplasms of uncertain histogenesis, infiltrate adjacent tissues and if not completely excised will recur locally. In this series, three patients at one time were treated with limited local excisions. Tumor persisted or recurred in all three. Five patients were treated with en bloc resection (following recurrences in two patients). None of these patients subsequently developed recurrent tumor. We believe that myxomas should be widely resected to prevent recurrence. The extent of the surgical resection should depend on the size, extent and location of the lesion.
