Oral soft tissue myxoma: report of a case and review of the literature.

The soft tissue myxoma of the oral cavity is a rare neoplasm. We report a case arising from the palate in a 15-year-old male. A review of the literature is presented with clinicopathologic, immunohistochemical, and ultrastructural data confirming the diagnosis. The pathogenesis and differential diagnosis are discussed with reference to documented association with fibrous dysplasia and "Carney syndrome."
