Abstract:
Anaplastic small cell carcinoma of the larynx is an uncommon neuroendocrine tumor. We report a case of this neoplasm of a 53-year-old male. The patient showed persistent hyponatremia accompanied with continuous loss of sodium in the urine, which resulted from inappropriate secretion of antidiuretic hormone (ADH). It is postulated that hyponatremia in this case was due to production of ADH by the tumor cells.
