Background: Primary squamous cell carcinomas of the thyroid are uncommon entities with less than 100 cases described in the literature.

Case report: We report on the imaging findings in a rare case of primary squamous cell carcinoma of the thyroid that was found to be the primary tumour of humerus and cervical lymph node metastases. Other sources of squamous cell cancer were ruled out by a careful search, including whole body computed tomography (CT), positron emission tomography/CT after intravenous F-18 fluorodeoxyglucose, complete otorhinolaryngological examination, and panendoscopy.

Conclusion: Primary squamous cell carcinomas of the thyroid, though very rare, should be included in the differential diagnosis of metastatic disease of squamous cell cancer.
