Neuroendocrine tumor mimicking a recalcitrant vocal fold granuloma: Appearances can be deceiving.

Posterior glottic lesions resembling granulomas unresponsive to conservative treatment should raise suspicion of a neoplastic condition. Although surgery is rarely recommended for arytenoid granulomas due to their high recurrence rate, histological evaluation is mandatory in cases of uncertain diagnosis. Clinicians should be aware that, although very rare, a laryngeal neuroendocrine tumor occurring in the posterior glottis can mimic the appearance of an idiopathic granuloma, presenting a diagnostic challenge.
