https://www.vetsurgeon.org/f/clinical-questions/27828/metastasis-in-a-dog-with-thyroid-follicular-carcinoma Hello, I have a case with a dog, 7y old, with a monolateral thyroid follicular carcinoma. The tumor has been removed and there were no histological evidence of vascular infiltration. The dog had a CT before surgery and no metastasis were found excepten-USTelligent Community 10https://www.vetsurgeon.org/thread/207410?ContentTypeID=1Sat, 26 Jan 2019 19:48:54 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:5f354152-0a88-495b-b1c4-85d27985d975orik<p>Actually it is the&nbsp;retropharyngeal&nbsp;one, on the same side of the tumor. The problem is that the lymph node is very small and even an FNA is difficult to perform.&nbsp;</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/207343?ContentTypeID=1Fri, 25 Jan 2019 12:09:01 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:ed68f841-c7ab-4f4b-be29-d6be40dfb3a5Anthony Dennison<p>Which lymph node would need removing? I&#39;m guessing if it&#39;s a thyroid carcinoma it would be a pre-scapular? If so, this should be able to be done in house without needing referral.</p> <p>Rather than removing the lymph node, could you check with a fine needle aspirate to see if there are tumour cells present or just an inflammatory reaction?</p><div style="clear:both;"></div>
