Skin growths (plaques), especially in the head and neck area in cats
When to visit the vet?
Non-urgent see a veterinarian within 2–3 days
ORANGE for severe itching, oozing/pus, rapid spread, fever/apathy, or if it involves a young/immunosuppressed cat (dermatophytosis/DDx). RED for extensive blistering/skin peeling or severe general condition.

Definition
Plaques are thickened areas of the skin that can often occur in the head and neck area of cats. These skin changes are often raised and can take on different sizes and shapes. They are a common symptom of various dermatological diseases in cats.
Can Occur with the Following Diseases:
Basics and possible causes
A cat’s skin consists of various layers that work together to provide protection against external influences. The epidermis is the outermost layer and serves as a barrier against bacteria and other harmful substances. Underneath lies the dermis, which contains nerves, blood vessels, and sebaceous glands. Healthy skin is flexible, smooth, and without irregularities.
Plaques develop when skin cells grow excessively or become inflamed. This can be triggered by a variety of factors, including allergic reactions, infections, or autoimmune diseases. In cats, the cause can often be complicated and involve a combination of environmental factors and genetic predisposition.
Allergies are one of the most common causes of skin plaques in cats. These can be triggered by flea bites, food, or environmental allergens such as pollen and dust. An allergic reaction leads to inflammation of the skin, which can promote the appearance of plaques.
Infections caused by bacteria, fungi, or parasites can also cause plaques. Bacterial infections often occur secondarily when the skin is damaged by scratching or biting. Fungal infections, such as those caused by dermatophytes (also known as ringworm), are also common causes of skin changes in cats.
Autoimmune diseases, in which the immune system mistakenly attacks the body’s own skin cells, can also lead to the formation of plaques. These diseases are less common in cats, but they can cause serious skin problems.
Typical accompanying symptoms
- Plaques: Raised, thickened skin areas that often have a rough surface and can enlarge over time. They often occur in the head and neck area.
- Itching: Cats with plaques often show intense itching and frequently scratch the affected areas, which can lead to further skin damage.
- Redness and inflammation: The skin around the plaques may appear red and inflamed, indicating an active inflammatory response.
- Hair loss: Hair loss may occur in the area around the plaques, either due to the damage the cat causes itself by scratching, or due to the underlying disease.
- Scaling: The affected skin may appear scaly and dry, indicating a disrupted skin barrier.
When to see a vet?
A visit to the vet is absolutely necessary if the plaques grow quickly or new plaques appear on other parts of the body. Early diagnosis and treatment are important to identify and treat the underlying cause.
If the cat shows signs of severe itching or discomfort, a vet should be consulted as soon as possible. Untreated itching can lead to severe skin damage and infections.
A vet visit is also advisable if the cat shows other symptoms such as lethargy, loss of appetite, or weight loss. These symptoms may indicate a systemic disease that needs to be treated.
Symptom recognition for the pet owner and veterinary diagnostic procedure
It is important for the pet owner to regularly examine the skin for changes. The appearance of plaques is often the first indication of a skin problem. Pay attention to behavioral changes in your cat, such as increased scratching or licking of certain areas of the body.
At the vet, the diagnosis begins with a thorough medical history and physical examination. The vet will inspect the plaques and check the skin for signs of inflammation, infection, or other abnormalities.
Additional diagnostic tests may be necessary to determine the exact cause of the plaques. These include skin scrapings to test for parasites, and cytological examinations to identify inflammatory cells or microorganisms. In some cases, biopsies may also be required to make an accurate diagnosis.
Allergy tests or elimination diets can be performed to determine whether food or environmental allergens are the cause. These tests help to identify specific allergens that should be avoided.
What the pet owner can do and professional therapy options
Until the vet visit, you should try to keep the affected skin areas clean and dry. Avoid letting the cat scratch the plaques, as this can further damage the skin. Wearing a protective collar can help prevent the cat from working on the affected areas.
Avoid applying any ointments or medications to the skin without veterinary advice. Some products can worsen skin problems or cause unpleasant reactions.
If the cat has severe itching, cool compresses can provide temporary relief. However, these should only be used for a short time to avoid further irritating the skin.
It is important to discuss all measures taken with the vet to ensure that they are appropriate for the specific situation of the cat. Correct and timely treatment by the vet can help to relieve the cat’s symptoms and prevent the progression of the symptoms.
Outlook on current research
Research on skin growths, especially in the head and neck area of cats, is a dynamic field that deals with the identification and characterization of the underlying mechanisms. In recent years, the understanding of skin plaques in cats has expanded, especially through the use of advanced diagnostic techniques such as dermatoscopy and histopathological examination. These technologies allow researchers to examine the microscopic changes in the skin in detail, which contributes to the development of more precise treatment approaches.
A focus of current research is on the immunopathology of such growths. Researchers are investigating how the cat’s immune system reacts to various environmental and genetic factors that lead to the formation of skin plaques. There is evidence that allergic reactions, autoimmune processes, or infections could play a role. Studies have also shown that certain breeds may be genetically predisposed, suggesting a hereditary component of the disease.
Another significant area of research is the role of nutrition and environmental factors. Scientists are investigating how different nutrients or environmental toxins can influence the development of skin plaques. There are ongoing studies examining the effect of omega-3 fatty acids and antioxidants on the skin health of cats, with the aim of developing preventive dietary strategies.
In the field of therapeutic research, scientists are focusing on the development of new treatment methods that specifically target the molecular mechanisms of plaque formation. This includes both pharmacological approaches and alternative therapies such as phototherapy. There is a growing interest in the use of immunomodulators, which can influence the cat’s immune system in such a way that an excessive reaction to stimuli that lead to plaque formation is prevented.
The future of research in this area promises to develop personalized medicine approaches based on the genetic and immunological profiling of cats. The ability to identify and specifically treat the specific causes of skin plaques in a cat could significantly improve the quality of life and reduce the need for general, potentially harmful therapies.
