1. What is lentigo?

Lentigo is caused by an accumulation of melanin, the pigment that gives skin its color, in the cat’s skin cells. It typically appears as small, flat, round or oval-shaped brown or black spots. These spots are most commonly found on the head, ears, and nose, areas exposed to the sun.

2. Causes of lentigo

Sun exposure is the primary cause of lentigo in cats. Similar to humans, cats with light-colored fur are more prone to developing these spots. Additionally, cats with hairless breeds or those with areas of alopecia (hair loss) are also at higher risk.

3. Signs and symptoms

Lentigo typically appears as flat, round or oval-shaped brown or black spots. These spots vary in size, ranging from a few millimeters to a centimeter or more. They usually appear on the head, ears, nose, and lips, areas most exposed to the sun.

4. Diagnosis

Diagnosis of lentigo is primarily based on a physical examination of the cat’s skin. Veterinarians may use a magnifying glass or dermatoscope to get a closer look at the spots and rule out other skin conditions. Biopsy, although rarely needed, may be performed in some cases for definitive diagnosis.

5. Treatment

Lentigo is generally harmless and does not require treatment. However, if the spots are bothering your cat or are a source of concern for you, your veterinarian may recommend various treatments such as:

Sunscreen: Applying sunscreen to exposed areas can help prevent further development of lentigo.
Cryotherapy: This treatment uses liquid nitrogen to freeze and destroy the affected skin cells.
Laser therapy: Laser therapy can be used to remove lentigo spots with minimal scarring.

6. Prognosis

With proper care and management, the prognosis for cats with lentigo is excellent. The spots are generally harmless and do not progress to any serious health conditions.

7. Prevention

While sunlight exposure is the main culprit behind lentigo, there are steps you can take to reduce the risk of your cat developing these spots:

  • Limit your cat’s sun exposure, especially during peak hours.
  • Provide your cat with shaded areas to rest in outdoors.
  • Apply sunscreen to your cat’s exposed areas if needed.

8. Importance of regular veterinary checkups

Regular veterinary checkups are essential for monitoring your cat’s overall health and detecting any changes in their skin. Early detection of lentigo allows for proper management and can help prevent potential complications.

9. Breeds at higher risk

Cats with light-colored fur, such as Persians, Siamese, and Burmese, are more prone to developing lentigo. Hairless breeds, such as Sphynx, are also at increased risk due to their lack of fur protection.

10. Differentiating lentigo from other skin conditions

Lentigo can sometimes be mistaken for other skin conditions such as melanoma, which is a more serious form of skin cancer. It is important to consult a veterinarian for a proper diagnosis to rule out any underlying health concerns.
