Achados dermatoscópicos em cães com dermatopatia inflamatória.

Abstract

Several studies have shown that dermoscopy may be very helpful in assisting the diagnosis of inflammatory skin diseases. Atopic dermatitis is an inflammatory, chronic and itchy skin disease, very common in dogs, whose diagnosis is based on the patient's history and clinical features, without a specific dermatological exam. With the need for increasingly specific, evolved and less invasive exams, the objective was to evaluate the use of digital videodermatoscopy exam as an auxiliary method for the diagnosis of canine atopic dermatitis and describe the dermoscopic findings. The study was carried out in the Dermatology Service of HOVET - UFRA and in the Melhores Amigos Pet Shop, both located in Belém - Pará. 50 dogs were evaluated independente of sex, age and breed; 25 dogs without dermatopathies (control group) and 25 dogs with inflammatory dermatopathies with a history and clinical signs of atopic dermatitis (DA group), with lesions in the axillary area underwent a clinical examination and underwent complementary dermatological tests and evaluated using dry dermatoscopy. In the DA group, the lesions observed in dermoscopy were: yellow serocrusts scales (100%, n = 25), pink / reddish background color (80%, n = 20). All dogs had whitish scales and / or plaques, scales adhered to the hair (80%, n = 20), whitish scales on the skin (72%, n = 18), whitish plaques (60%, n = 15), reddis serocrusts scales (40%, n = 10), representing results similar to the dermatoscopy of human atopic dermatitis. The results of this study suggest that videodermatoscopy was able to describe the structural characteristics of the dogs ́skin with and without inflammatory skin dermatopathies and has shown great potential as a screening method and pre- diagnosis for CAD diagnosis, emphasizing that the characteristic of any dermatopathy must be evaluated taking into account the general clinical context of it.
