Giant lipoma of the larynx: a case report and literature review.

Fewer than 15% of lipomas occur in the head and neck. To date, fewer than 100 cases of laryngeal lipoma have been reported in the literature. Typical clinical manifestations include dysphagia, dyspnea and hoarseness, as well as the presence of a smooth or pedunculated mass seen endoscopically and a low attenuation mass on computed tomography scan. Pathologic sections commonly reveal a tumor consisting of mature adipocytes, which is often encapsulated. Treatment of laryngeal lipoma varies from conservative total endoscopic removal to external surgical approaches. The following is a report of a single case of laryngeal lipoma, including pathologic and radiologic findings, as well as a review of the literature.
