Plain-English summary
A dog was diagnosed with sarcoptic mange, a skin condition caused by scabies mites, which can be hard to identify because its symptoms are similar to other itchy skin problems. To confirm the diagnosis, the veterinarians used a technique called entodermoscopy, which allows them to look closely at the skin. They found specific features of the mites, including their unique shapes and the tunnels they create in the skin. This method is helpful because it is non-invasive and provides clear images that can help confirm the presence of these parasites. Overall, the entodermoscopy technique worked well for diagnosing the dog's condition.
Abstract
BACKGROUND: Diagnosing sarcoptic mange in dogs can be challenging because the clinical signs overlap with those of other pruritic conditions. Entodermoscopy has emerged as a promising technique for the rapid confirmation of suspected scabies mite infestation. OBJECTIVE: To describe the dermoscopic features of sarcoptic mange in a dog. ANIMALS: A dog with sarcoptic mange was examined via dermoscopy after skin scraping confirmation. RESULTS: Distinctive dermoscopic features included: the mite-gallery unit (MGU) and specific mite structures, such as characteristic 'Δ'-shaped gnathosomes, eggs and burrows. Stercoraceous bullets, wake signs and grey-edged line signs also were observed. Polarised and non-polarised light exhibited distinct diagnostic capabilities. Digitally enhanced dermoscopy provided additional details. CONCLUSIONS AND CLINICAL RELEVANCE: The MGU describes the anatomical and functional aspects of scabies mites as epidermal parasites and qualifies dermoscopy as a non-invasive diagnostic tool.
