Skin tumors in dogs are relatively rare clinically. The following are several clinically identifiable skin tumors:

1) Epidermoid cyst

This These tumors can occur in all parts of the dog's body, but mostly on the back. The tumor is soft and brittle, and the contents are dry.

2) Sebaceous gland tumor

Benign tumor more common in aged dogs. The tumor surface is pale, firm, multilobular, and without coat. If it appears in the dog's mouth, it may develop into Ulcers, surgical excision works well.

3) Breast cell tumor

Clinically, the dog's breasts are enlarged, pale, hard, smooth, and may form ulcers. Surgical resection results are good.

4) Histiocytoma

Due to the rapid growth of the tumor, nodules with obvious epidermal boundaries or local ulcers are rare in clinical practice. They mainly occur on the face and feet of young dogs. This cell tumor can dissipate on its own.

5) Papillomas

Older dogs are more common. Papillomaviruses have been reported to cause papilloma in dogs.

6) Basal cell tumors

Mostly on the face and limbs. The tumor area grows slowly and may develop ulcers, melanogenesis, and associated melanoma.

VII) Cutaneous Lymphoma

In dogs with systemic lymphoma, subcutaneous lymphoma may appear, which is indicated by epidermal redness, alopecia and dandruff. Further diagnosis requires tissue biopsy.

VIII) Melanoma

The tumor is black, hairless or less hairy. Generally, there is no inflammatory reaction, and the effect of surgical resection is good.
