Introduction: The cervical region is a frequent site of neoplastic pathologies, including primary cancer and secondary lesions. The incidental discovery of thyroid carcinoma during surgery for upper airway pathology is rare.

Observation: We report the case of a 69-year-old male patient, a chronic smoker weaned 30 years ago, who underwent total laryngectomy with cervical lymph node curage. Histopathological examination revealed a moderately differentiated keratinizing squamous cell carcinoma classified as pT4aN0Mx. The Lymph node dissection revealed a metastatic lymph node without capsular rupture from a papillary thyroid carcinoma in the right IIa territory. Two months later, the patient underwent total thyroidectomy, with histopathological examination of a 7mm infiltrating vesicular variant papillary microcarcinoma of the right lobe with vascular emboli classified as pT1aN1bMx, at high risk of recurrence. The patient was scheduled for radioiodine therapy.

Discussion and conclusion: The association of thyroid carcinoma with laryngeal cancer is rare. There is no standardized therapeutic protocol for the simultaneous treatment of laryngeal and thyroid cancer. Hence the importance of a thorough examination of the cervico-facial region during surgical treatment of cervical neoplasia.
