Metastatic squamous cell carcinoma
of the tonsil in a 10-year-old Belgian Shepherd. This large cervical mass
extended through the cervical soft tissues to the pharynx and to the area
where the left tonsil, excised 4 months before, was previously located.
On the right, one can see the macroscopic appearance of the mass’s
cut surface, which exhibits mucinous-like areas.
