Dorsal to the canine teeth the lesions are about 7x10mm, and almost rectangular. The hard palate lesions are directly adjacent to 108/109 and 208/209 about 3mm wide. They certainly look ulcerated.</p> <p>If this was skin I would be very suspicious of drug eruption or autoimmune and I would certainly biopsy these, so I will talk to the owner about biopsying the oral mucosa.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/226791?ContentTypeID=1Tue, 17 Nov 2020 20:15:42 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:34c7b8ba-375c-421d-a29a-2fcbae070cb6Rachel Perry<p>None that I&#39;m aware of- have you biopsied?
