Abstrakt: CT neck with IV contrast showed a 4.5cm laryngeal mass (Image 2) and direct laryngoscopy and microscopic laryngoscopy with biopsy of the tumor on the left vocal cord with multiple biopsies taken of the terminal vocal cords finally revealed squamous cell carcinoma. This has been shown in another laryngeal carcinoma but was not seen with recurrence of the tumor.[1] The mechanisms leading to the associated hyponatremia could have been related to tumor ADH productions or other factors yet unknown.[2] Other types of squamous cell carcinomas are known to cause SIADH as a paraneoplastic syndrome, particularly squamous cell carcinoma of the tongue.[3] It has not been well documented to be from squamous cell carcinoma of vocal cords.
