A basal cell tumor is a type of skin cancer that affects dogs. Basal cells are located in the deep epidermal layer of the skin. Basal cell tumors are abnormal masses of these cells; they can be benign or malignant.

Causes
-
There is no know cause for basal cell tumors; however, prolonged sun exposure appears to increase the risk.
Appearance
-
Basal cell tumors are usually firm, hairless masses that may appear ulcerated. They can be attached firmly or have a stalk.
Prevalence
-
Canine basal cell tumors are not very common. When present, they usually appear on middle-aged and older dogs. Common locations include the head, neck, and shoulders. Poodles tend to be predisposed to these tumors.
Treatment
-
Surgical removal of the tumor is necessary, and the tumors usually do not return.
Prognosis
-
Surgery is usually curative for benign tumors. Malignant tumors, also called basosquamous cell carcinomas, will invade local tissue but rarely metastasize. Surgical removal of the tumor and surrounding tissue is usually curative as well.
