Morphological changes in the skin of dogs at sarcoptosis

Abstract

The results of histological studies of the skin of dogs with sarcoptosis are presented. Studies have shown that with different forms of sarcoptosis in dogs, histological changes occur in all layers of the epidermis and dermis, regardless of the location of ticks. The nature of these changes varies and depends on the severity of the disease. Depending on the form of the disease, similar pathomorphological changes of the skin severity were noted. We observed spongiosis, interstitial edema, hyperkeratosis of the epidermis, inflammatory and melanocytic infiltration of the epidermal layer of the skin. In the dermis, with deep skin lesions, necrosis foci and pronounced interstitial edema, mainly of the papillary layer, less often of the mesh layer, were detected. In generalized severe form in some areas of the dermis and epidermis completely lost histological structure.
