The patient was a 10-year-old female, spayed, Poodle dog with a subcutaneous mass in the ventral region of the neck. Fine needle aspiration was performed yielding a diagnosis of thyroid adenocarcinoma, which was confirmed by histopathology as solid follicular cell thyroid adenocarcinoma, after a right extracapsular thyroidectomy. Canine Total Thyroxine and Free Thyroxine (cTT4) and (cFT4) were evaluated on 2 occasions; the first time on day 42 and the second one on day 63 of evolution. Both evaluations showed a decrease in cTT4 and cFT4 with an increase in Canine Thyroid-Stimulating Hormone (cTSH) compatible with hypothyroidism, secondary to unilateral thyroidectomy. Treatment with levothyroxine (Trioxil®; Alphachem) at a dose of 25 μg/kg orally twice a day was given.
