Metastatic spread to the ribs in a 15‐year‐old, male, neutered, Irish setter is reported occurring secondary to an oral squamous cell carcinoma (SCC). The dog presented with a history of a rapidly growing SCC of the right upper incisive region, which was confirmed by histopathology as a SCC. Thoracic radiographs showed bony lesions associated with the body of the right third rib, and the fifth and seventh costal cartilages. A rostral partial maxillectomy was performed as palliative treatment for the oral mass and a core biopsy of the lesion on the third rib was performed. The rib lesion was identified histopathologically as a metastatic SCC. A review of the literature of oropharyngeal SCC and the metastatic potential of non‐tonsillar SCC is presented, in particular metastatic bone disease. This case report suggests possible implications of metastatic bone disease for treatment and prognosis for future cases of non‐tonsillar SCC.
