Lentigo in cats - Types, symptoms and treatment

See Cats files

Feline lentigo is a skin disorder that consists of the accumulation of melanocytes on the basal layer of the epidermis. Melanocytes are cells that contain a pigment called melanin, which is dark in color. Due to this accumulation, our cats present black spots in places like the nose, eyelids, gums, lips, or ears.

While lentigo is a completely harmless, benign and asymptomatic process, it must always be differentiated from a malignant and aggressive tumor process called melanoma. The diagnosis is made with the taking of biopsies and their histopathological study. It has no treatment, it is simply an aesthetic defect, but it does not cause any problems for cats. Keep reading this AnimalWised article to learn more about the lentigo in cats, your symptoms and diagnosis.

What is lentigo in cats?

Lentigo (lentigo simplex) is an asymptomatic dermatological process characterized by the formation of one or multiple black spots or macules or dark in color at the dermo-epidermal cutaneous junction. These lesions consist of an accumulation of melanocytes (melanocytic hyperplasia), the cells that accumulate the pigment called melanin in the cutaneous basal layer, without elevation or thickening of the skin in these accumulation sites..

The most commonly affected areas are:

  • Nose.
  • Gums.
  • Eyelids.
  • Ears.
  • Lips.

its about a process totally benign that only means an aesthetic problem for feline caregivers, however, your cat will not even find out that he has it and will continue to be happy.

Causes of lentigo in cats

The lentigo is a genetic disorder with autosomal recessive inheritance. While it has been thought that a papillomavirus may be involved in canine lentigo and a biochemical relationship has been found between post-inflammatory hyperpigmentation and inflammatory reactions that can cause lentigo, they are actually all hypotheses..

When it occurs in cats, it is usually seen in red, orange or cream coat cats, although exact pathogenesis has not been established, beyond inheritance.

With regard to age, they usually appear in younger or older cats.

¿Lentigo in cats is contagious?

No, it is not a contagious disease, since it is not caused by any microorganism. It is a totally individualized process that appears or not according to the inheritance of the feline.

Symptoms of lentigo in cats

Especially if your cat is reddish or orange, of greater or lesser intensity. The black spots on the chin if accompanied by wounds, scabs and raised edges can be indicative of feline acne, not of lentigo.

In feline lentigo, cats present blackish, brown, or grayish spots dark spots that can spread or grow over time. They are not pruritic or malignant as they do not proliferate in nearby tissues or internal layers, nor because they have the ability to metastasize to other places in the feline's body..

These lesions, although they can appear at any time, often begin before one year of age or at an older age.

Diagnosis of lentigo in cats

The diagnosis of lentigo in cats is simple, with the observation of spots small black spots on the nose, ears, eyelids, gums or lips. However, it must always be differentiated from other diseases that can be confused with this process, such as:

  • Melanoma.
  • Superficial pyoderma.
  • Demodicosis.
  • Feline acne.

The definitive diagnosis is based on taking biopsy samples and send them to the laboratory for histopathological analysis. This analysis will show abundant cells with melanin pigment (melanocytes).

It must be taken into account that if these lesions are modified in relation to their extension, circumscription of the edges, elevation or appearance of spots in an area other than those indicated, melanoma should be considered, a malignant process with a much worse prognosis. In this case, histopathology will also show the definitive diagnosis..

Treatment of lentigo in cats

Lentigo in Cats no treatment, no need, it does not alter in any way the quality of life of the feline. While in human medicine thermal abrasion has been used in order to eliminate these lesions, in feline veterinary medicine it is not performed.
