Metastasis to the thyroid gland from a tonsil squamous cell carcinoma

We present a case of rare metastasis of tonsil squamous cell carcinoma to the thyroid gland, after 2 years of treatment without recurrence at the primary site. The patient had incidental finding of a nodule in the left lobe of the thyroid gland during a screening scan for his previous tonsil squamous cell carcinoma that was treated surgically 2 years ago. The patient was completely asymptomatic with normal thyroid function tests. After further investigations and discussion in the MDT meeting, the patient underwent left thyroid lobectomy as a definitive treatment for his thyroid metastasis.
