Nasosinal Tumors

Nasal Neoplasia (Nasosinal Tumors)


Tumors affecting the nasal cavity are usually slow growing and can be any one of several forms of cancer including adenocarcinoma, squamous cell carcinoma and undifferentiated carcinoma which are most common.  Less common forms include fibrosarcoma, chondrosarcoma, osteosarcoma and undifferentiated sarcoma. These tumors are usually slow to metastasize, but can cause severe discomfort and pain to the dog and unfortunately in most cases are ultimately fatal.

Symptoms: Excessive Sneezing, bloody or purulent discharge from the nose and/or eyes, deformity of the nose/muzzle/face/eyes, in some cases loose teeth or difficulty breathing may occur.

Treatment Options:  Examination to rule out other causes such as foreign body, fistula or infection. Radiographs, CT scan, and biopsy may be used to determine the extent and malignancy of the tumor.  Surgery may or may not be be indicated along with other treatments such as radiation, depending on the location and progression of the tumor.
