Myxoma is a rare nonepithelial neoplasm of the larynx frequently misdiagnosed as a large vocal polyp due to its slow-growing nature. Myxoma is a benign but often infiltrating neoplasm of uncertain mesenchymal cell origin, characterized by irregular round, spindle or stellate cells within a matrix containing abundant mucoid material, scant vascularity and a variable meshwork of reticulum and collagen. We report one case of myxoma with life-threatening dyspnea requiring tracheotomy.
