Squamous cell carcinoma
Squamous cell carcinoma is a malignant tumor of skin and mucosal surface cells that affects dogs on the skin, nail beds, and within the mouth. Cutaneous and digital forms are locally invasive and may be linked to sun exposure or pigmentation, while oral and tonsillar forms behave more aggressively. Lesions often appear as non-healing ulcers, crusts, or proliferative masses. Early wide excision offers the best outcome.
