ABSTRACT
Even with 1% of the incidence, laryngeal neuroendocrine tumors are the second common tumors in larynx; as a subtype, typical carcinoid tumors are extremely
rare. We presented a case of laryngeal typical carcinoid tumor and we discussed diagnostic criteria and treatment of these tumors. A 57-year-old male with a 3
months history of hoarseness was examined endoscopically and a laryngeal mass on left supraglottic area was seen. High levels of serum calcitonin were detected.
The histopathological analysis of biopsy material was typical carcinoid tumor. Laryngeal tumor resection and left neck dissection were performed. The histopathologic
result was TTF 1 and calcitonin positive primer laryngeal typical carcinoid tumor with cervical lymphoid metastasis. Serum calcitonin level returned to normal levels
postoperatively. The distinction between laryngeal carcinoid tumors and metastasis of thyroid medullary carcinoma are difficult histopathologically. So, laryngeal
carcinoid tumors should be kept in mind in these circumstances.
