tumors diagnosed in dogs and Table 2 lists the most common tumors diagnosed in cats. No confirmed diagnosis can be made by palpation alone. A biopsy is the basic tool that allows removal and examination of cells from the body to determine the presence, cause, or extent of a disease process. Samples for analysis can be
The most common benign canine skin and subcutaneous benign tumors include lipomas (8%), histiocytomas (8–12%), perianal gland adenomas (8–12%), sebaceous gland adenomas/hyperplasia (4–6%), trichoepitheliomas (4%), papillomas (3%), and basal cell tumors (4–5%).
Basal cell tumors are one of the most common skin tumors in dogs and cats. A basal cell carcinoma is a type of basal cell tumor that is malignant or cancerous. Fortunately, less than 10% of basal cell tumors are malignant.
Canine basal cell tumors most commonly develop in middle-aged to older dogs. Many breeds are predisposed, especially Wirehaired Pointing Griffons and Kerry Blue and Wheaten Terriers. These tumors are found most commonly on the head (especially the ears), the neck, and forelimbs.
In patients with naevoid basal cell carcinoma syndrome (NBCCS), close surveillance and regular skin examinations are required to diagnose and treat BCCs at early stage.
Most tumors diagnosed as basal cell tumors via cytology are easily cured with narrow surgical excision. If histopathology reveals a basal cell carcinoma, complete staging, including locoregional lymph node aspiration, chest radiography, and abdominal ultrasonography, is recommended.
Symptoms of Basal Cell Tumor in Dogs. Basal cell tumors present as firm, well-circumscribed, hairless masses that are typically located around the dog’s head, neck, or forelimbs. They occasionally appear pigmented, and they vary from 1 centimeter to 10 centimeters in size.
