We describe the case of a 41-year-old man with hoarseness and a hard, fixed mass in the anterior cervical region. He was referred to our endocrinology service for evaluation of possible thyroid cancer. The results of laboratory tests of thyroid function were normal. Indirect laryngoscopy revealed paralysis of the left hemilarynx and the presence of a large vegetating lesion. Computed tomography of the neck disclosed the presence of a mass in the anterior region, along with invasion and destruction of the adjacent structures. The cytologic diagnosis was established by analysis of a fine-needle aspiration biopsy specimen, which revealed a squamous cell carcinoma. The final diagnosis was carcinoma of the larynx.
