Neural and neuroendocrine tumors of the larynx

Benign and malignant neural and neuroendocrine tumors of the larynx are uncommon enough that knowledge about them is sparse, coming from single case reports and literature reviews. We have reviewed the clinical behavior, pathologic findings, treatment, and outcome in 42 patients seen at one institution from 1907 to 1986. In some cases, electron microscopy or immunocytochemistry, or both, may be needed to reach the correct diagnosis. Treatment is largely determined by the histopathologic features, size, and location of the tumor. The most common sites are the supraglottic region and posterior larynx. Most tumors are treated by conservation surgery, including transoral excision; however, some are aggressive and require larger surgical procedures, including wide-field laryngectomy and complete neck dissection.
