Plain-English summary
Diagnosing sarcoptic mange, a skin condition caused by scabies mites, in dogs can be tricky because its symptoms can look like other itchy skin problems. A recent study focused on using a technique called entodermoscopy, which allows veterinarians to look closely at the skin and identify the mites. In this case, a dog with confirmed sarcoptic mange was examined, revealing unique features of the mites, including their shape and the tunnels they create in the skin. The study showed that this method is a useful, non-invasive way to confirm the presence of these mites. Overall, the findings suggest that entodermoscopy can effectively help diagnose sarcoptic mange in dogs.
Abstract
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.
