Any evidence of Bursal enlargement?</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/38396?ContentTypeID=1Wed, 01 Jun 2011 08:32:17 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:260fad09-7fe2-404a-9db1-34c6e5de8c83Martin Jones<p>Thanks, Marie</p> <p>I was always under the impression that Marek&#39;s lumps were a little smaller and less randomly distributed. But there was nothing internally - I went in looking for evidence of nerve tumours, but didn&#39;t find a thing. Otherwise, Marek&#39;s kind of fitted the bill nicely, as all the birds were young and all died. Unfortunately, the clients weren&#39;t able to give me any clues as to previous symptoms etc.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/38390?ContentTypeID=1Tue, 31 May 2011 22:25:45 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:f19f868b-0287-419f-a914-cf204fd99c91Marie Kubiak<p>Mareks can cause skin nodules of lymphoid-type tissue. What symptoms did the others show before they decided to die? Did you look at sciatic nerve trunk? Any internal lumps? I would try and do impression smears/histo on any remaining lumps in the fridge and look for lymphoblasts.</p> <p>Marie</p><div style="clear:both;"></div>
