Skin Growths

The 3 Most Common Skin Growths (Benign) in Dogs

Hey, pet parents! Dr. B here from Pet Health, continuing our October series on lumps and bumps. So far, we’ve covered what to do when your pet has a lump and how to distinguish between benign and malignant growths. Today, we’re diving into the three most common benign skin growths I see in dogs: lipomas, epidermal (inclusion) cysts, and sebaceous adenomas. Always consult your vet before diagnosing or assuming a growth is benign, as even benign growths can cause problems.

Lipomas

Lipomas are benign, slow-growing masses that develop under the skin. They are most commonly seen in older dogs and certain breeds, such as Labrador Retrievers, Beagles, and Dachshunds. The exact cause is unknown, but obesity and genetics are considered risk factors. Lipomas are typically soft and movable, and while they often require no treatment, they can occasionally impede motion or cause discomfort.

Benign vs. Malignant: Understanding Tumors in Pets

Lipoma

Key Points about Lipomas:

  • Appearance: Soft, movable lumps under the skin, usually painless.
  • Diagnosis: Physical examination and fine needle aspiration (FNA) to rule out other types of tumors.
  • Treatment: Often left untreated unless they impede movement or cause discomfort. Surgical removal is usually curative for simple lipomas.

Epidermal (Inclusion) Cysts

Epidermal cysts, or follicular cysts, are common benign skin tumors. They form due to fluid accumulation in the hair follicle and are typically harmless. However, they can become infected and painful. Certain breeds, such as Basset Hounds, Schnauzers, and Shih Tzus, are more prone to developing these cysts.

Epidermal Cyst

Key Points about Epidermal Cysts:

  • Appearance: Firm, round (often pea-sized) swellings directly under the skin, usually painless but can become red and painful if infected.
  • Diagnosis: Fine needle aspiration to examine the cyst contents under a microscope.
  • Treatment: Monitoring if not bothersome; antibiotics if infected; surgical removal if causing discomfort or cosmetic concern.

Sebaceous Adenomas

Sebaceous adenomas are benign tumors originating from the sebaceous glands, which produce an oily substance to lubricate and protect the skin. These tumors are usually slow-growing and non-invasive, commonly found on the head, ears, and trunk. Breeds like Cocker Spaniels, Beagles, and Miniature Schnauzers are more frequently affected.

Sebaceous Ademona

Key Points about Sebaceous Adenomas:

  • Appearance: Round or oval growths with irregular surfaces, ranging from pale yellow to dark brown.
  • Diagnosis: Physical examination, with biopsy or removal if needed for confirmation.
  • Treatment: Often a cosmetic concern, but removal may be recommended if the growth is bleeding, itchy, or interfering with grooming.

I hope this blog helps you understand more about common benign skin growths in dogs and how to manage them.

Monitoring your dog’s skin for new or changed growths is crucial for their health and well-being. Regular at-home checks can help you spot any changes early, and always consult your veterinarian if you notice new growths or significant changes in existing ones. Remember, even benign growths can cause problems, so seeking professional advice is essential to ensure your pet stays happy and healthy.
