What is EOS in cats? - briefly
EOS in cats refers to Eosinophilic Granuloma Complex, a group of inflammatory skin conditions characterized by lesions and ulcers, often caused by allergic reactions or immune system disorders.
What is EOS in cats? - in detail
EOS, or eosinophilic granuloma complex, is a group of skin disorders commonly observed in cats, characterized by the presence of eosinophils, a type of white blood cell, in affected tissues. This complex typically manifests in three primary forms: eosinophilic plaque, eosinophilic granuloma, and indolent ulcer. Eosinophilic plaques are raised, red, and often ulcerated lesions that frequently appear on the abdomen, thighs, or other areas of the skin. They are intensely itchy and can cause significant discomfort to the affected cat. Eosinophilic granulomas, on the other hand, are linear or nodular lesions that can develop on the skin, oral cavity, or paws. These lesions are less pruritic but may lead to swelling, pain, or difficulty in eating if they occur in the mouth. Indolent ulcers, also known as rodent ulcers, are well-defined, non-painful lesions that typically appear on the upper lip, though they can also affect other areas of the oral cavity. The exact cause of EOS in cats remains unclear, but it is often associated with hypersensitivity reactions, such as allergies to flea bites, food, or environmental allergens. Additionally, genetic predisposition and immune system dysregulation may contribute to the development of these conditions. Diagnosis is typically based on clinical signs, history, and cytological or histopathological examination of the lesions. Treatment often involves addressing the underlying cause, such as flea control or dietary changes, and may include corticosteroids, antihistamines, or immunosuppressive drugs to manage inflammation and symptoms. In some cases, antibiotics are prescribed to prevent or treat secondary bacterial infections. Early intervention and proper management are essential to improving the cat's quality of life and preventing recurrence of the lesions. Regular monitoring and follow-up with a veterinarian are recommended to ensure the effectiveness of the treatment plan and to make adjustments as needed.
