- Squamous cell carcinoma of the nasal planum is an uncommon tumor in dogs. Unlike cats it is not associated with a lack of pigmentation and exposure to UV irradiation.
- Physical examination initially reveals superficial crusting lesion, progressing to more thickened, ulcerated and indurated mass with time. Evaluate regional lymph nodes for possible metastasis. Uncommonly can be proliferative.
- Enlarged regional lymph nodes do not necessarily indicate metastasis, since reactive nodes are common. Enlarged lymph nodes should be evaluated by aspiration cytology .
- Completely excised lesions have a good prognosis whereas incompletely excised tumors recur but this may be delayed.
Expected response to treatment
- Only lack of recurrence a periodic rechecks will determine completeness of response.
