Sebaceous Gland Tumors In Dogs

The sebaceous glands are responsible for producing oil called sebum, and secreting it into the hair follicles and onto the surface of the skin. Sebaceous gland tumors are widespread in dogs.

Sebaceous gland hamartomas are single elongated or circular tumors commonly discovered in dogs soon after birth. They are about 2 inches (5 cm) in diameter or length.

Sebaceous gland overgrowth, also known as hyperplasia, tends to develop in elderly cats and dogs. It looks like a shiny, horn-like lump not more than 0.4 inches (1 cm) in width. The dog breeds most susceptible are Welsh Terriers, Manchester, and Wheaten, with their heads and abdomen being affected the most.

Sebaceous gland adenomas are frequently impossible to differentiate from sebaceous gland overgrowth, though they tend to be bigger (normally more than 0.4 inches [1 cm] thick). Elderly dogs are more prone to such tumors, and vulnerable breeds include Alaskan Malamutes, Coonhounds, Huskies, English Cocker Spaniels, Samoyeds, and Cocker Spaniels. Sebaceous gland adenomas are often numerous and may crop up anywhere on the body, though are normally found on the head. They tend to be filled with pus and covered with a crust.

Sebaceous gland adenocarcinomas are a type of tumor that affects the sebaceous glands. They are rare, malignant, and are prevalent in male middle-aged or elderly dogs. The breeds most at risk are West Highland White Terriers; Cavalier King Charles Spaniels; Scottish White Terriers; Cairn White Terriers; and Cocker Spaniels. The tumors may be impossible to differentiate from sebaceous epitheliomas. They extend on the skin and may later form on lymph nodes.

Surgery is non-compulsory for benign sebaceous gland tumors when a diagnosis is established. In case of malignant adenocarcinomas, surgery is the preferred treatment. Your veterinarian will get rid of not only the tumor but also tissue surrounding the tumor, as well as affected lymph nodes. Additionally, chemotherapy and radiation treatment may also be recommended.

Smooth Muscle Tumors of the Skin

These are rare tumors, with very little being known about them. There are some that have been diagnosed in cats and dogs, but they have been malignant. Majority of these tumors are solid masses that can be felt through the skin. Surgical treatment is an option used to get rid of the tumor.
