Hamartoma of the larynx: an unusual cause of upper airway obstruction.
Hamartomas are rare lesions in the larynx. Both clinical and histopathological findings may be misleading to both the physician and the pathologist in terms of diagnosis. A 51-year-old female with the complaints of nonproductive cough and severe dyspnea lasting for a year was found to have a subglottic, submucosal mass almost totally obstructing the laryngeal lumen. Excisional biopsy was performed under suspensory direct laryngoscopy. Histopathological examination showed numerous, large, distended blood vessels, some of which had prominent thickened walls and mature adipose tissue beneath the surface epithelium. The final diagnosis was hamartoma, but we discussed its validity and other possible identifications in accordance with the literature.
