Basal cell tumors vary in size, from a few centimeters to inches in diameter, and most commonly appear as single, firm, hairless, raised masses in the skin, often on the head, neck, or shoulders. Occasionally, they may be cystic or ulcerate, and some may stick out like stalks from the skin surface.
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%).
Determination of tumor type by histologic examination of a biopsy sample should be the basis for all subsequent steps in oncology case management. Diagnostic staging determines the extent of local disease and presence or absence of regional or distant metastasis.
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.
Topical therapies (5% imiquimod, 5% fluorouracil) and destructive approaches (curet-tage, electrocautery, cryotherapy, laser ablation) should be considered in patients with low-risk superficial BCC. Photodynamic therapy is an effective treatment for superficial BCC and thin nodular BCC.
16 lis 2023 · Basal cell tumors are one of the most common skin tumors in dogs and are almost always benign, or non-cancerous. When basal cell tumors are malignant, or cancerous, they are called basal cell carcinomas. Basal cell carcinomas can sometimes be mistaken for benign basal cell tumors.
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.
