Abstract:
Neuroendocrine carcinoma (NEC) is a rare form of hormone-secreting tumor. NECs originate from the epithelial cells of the larynx and account for less than 1% of the laryngeal neoplasm. Most cases of NECs are diagnosed by pathological confirmation after surgery. The terminology of laryngeal NEC has been a source of confusion. In 2017, World Health Organization newly categorized laryngeal NEC; as a result, the large cell type, which has been the main target of disagreement, was finally included into a subtype of poorly differentiated NEC. We report a case of a 58-year-old male with a growing granulomatous mass in the posterior supraglottis. The granuloma was removed by surgical excision when the size of the mass increased. He was diagnosed with the large cell type laryngeal NEC by pathological confirmation. He underwent postoperative radiotherapy and is currently being followed up in our outpatient clinic without evidence of recurrence.
