| Stratified squamous epithelium covering the tissue is ulcerated. The epithelial tissue is proliferative and contiguous in places with a mass present below. The underlying collagen is infiltrated by a solid mass of proliferating squamous epithelial tissue. The epithelial tissue occurs as masses, trabeculae or nests with minimal stromal tissue. The epithelial cells are variable in size; they have large nuclei with prominent nucleoli; mitotic figures are frequent.

question="In view of the successful elimination of the primary, what do you consider the patient’s long-term prognosis to be?"

choice1=""

choice1="Excellent - he should be cured. "

choice2=""

choice2="Very good - the risk of local recurrence or metastatic spread is low. "

choice3=""

choice3="Good - he may develop metastatic spread, but not for years. "

choice4=""

choice4="Fair - this was a large tumour that had been present for months before detection so recurrence or metastatic spread is still a possibility. "

choice5=""

choice5="Poor - he would be unlikely to live more than 6 months. "

feedback1=""

feedback1="'''Incorrect'''. This is what we would hope but local recurrence or metastatic spread is still a possibility."

questionnumber="16"

questionnumber="16"

question=""

question="Your client had a cat that had exactly the same problem and he wants to know if she could have had the same treatment. What do you tell your client about oral squamous cell carcinoma in the cat?"

choice1=""

choice1="The cat could have had neoadjuvant radiation followed by a caudal mandibulectomy with the same outcome. "

choice2=""

choice2="We never perform mandibulectomies on cats because they will not tolerate them. "

choice3=""

choice3="Oral squamous cell carcinoma of the mandible of the cat is very sensitive to radiation so radiation is the sole treatment. "

choice4=""

choice4="Oral squamous cell carcinoma of the cat does not respond well to radiation and the results have been poor with conventional protocols. "

choice5=""

choice5="Cats do not get mandibular squamous cell carcinoma; it is always sublingual. "

correctchoice="3"

correctchoice="4"

feedback1=""

feedback1="'''Incorrect'''. Review oral squamous cell carcinoma in the cat."
