What do you think of these pharyngeal mucosal lesions? I discovered this on a 3 yr old cavalier. He did not have severe periodontal dz (yet) but needed 15 extractions d/t widened periodontal ligament spaces, periapical abscesses, crowding, and widened pulp cavities. I do not have rads with me but included pix of lesions. Inflammatory reaction? Other???
