Introduction: The association of thyroid carcinoma with squamous cell carcinoma of the larynx is very rare, with few clinical cases reported in the literature.
Case report: We report the case of a 63-year-old patient with no significant medical history who presented with progressive dysphonia. Fiberoptic examination revealed a budding lesion. CT scan showed a tumor process centered on the right vocal cord, with negative extension findings. The patient underwent right laryngectomy with hemithyroidectomy and right recurrent laryngeal nerve dissection. Histopathological examination revealed two foci of well-defined, non-encapsulated, 3mm each, papillary microcarcinoma of the thyroid, vesicular variant, with no metastatic lymph nodes found in the totalization and central lymph node dissection. The patient was classified as low risk of recurrence. Subsequently, the patient received radiotherapy/chemotherapy as part of the management of the squamous cell carcinoma and was started on suppressive therapy with l-thyroxine.
Discussion and Conclusion: Surgical treatment of squamous cell carcinoma of the larynx is an unusual circumstance for the discovery of thyroid cancer, most often representing a histological surprise. According to the literature, there is no well-established therapeutic protocol, but the prognosis is closely linked to upper aerodigestive tract cancer.
