Summary. Changes at the cellular level are described in all organs and tissues during pathomorphological study of the large horned cattle with nodular dermatitis. The obtained by the authors data confirm the serious changes in the whole organism. The parenchymal organs and connective tissue, as well as the skin are involved in the pathological process. The greatest lesions are noted in the skin. The onset of edema in the dermis is associated with vascular thrombosis, which leads to coagulation necrosis of surrounding tissues. Fibrinoid necrosis of deep layers of the skin with violation of epithelialization in the focus, infiltration by polymorphic cells with a predominance of lymphocytes, decay of cells by the type of karyorexis are registered. Eosinophilic exudate was observed on the surface of the larynx and polymorphic cell infiltration of the laryngeal wall during the study of histological sections of the larynx. Authors also described fragmentary fibrinoid necrosis of artery walls, perivascular edema and infiltration of lymphocytes, leukocytes, histiocytes in the cardiac muscle. Interstitial small focal accumulations of lymphocytes, histiocytes in the stroma with swelling and homogenizing of fibrous structures eosinophilic clusters, interstitial hemorrhage, diffuse infiltration with lymphocytes in the wall of the stomach was also recorded. Infiltration of leukocytes, lymphocytes, disturbance of the structure of the villi in the form of homogenization and basophilic staining revealed in the small intestine; serous-purulent inflammation with fibrinoid necrosis of the walls of the vessels, focal emphysema and hemorrhages in the lungs; interstitial fibrinous-purulent infiltrates with focal fibrinoid necrosis of the stroma, necrosis of the epithelium of the convoluted tubules in the kidneys. The above mentioned morphological changes must be taken into account in confirming the diagnosis on nodular dermatitis in large horned cattle.

Keywords: Lumpy skin disease, Ehrlich hematoxylin, skin, necrosis, microthrombi, heart, fibrinoid necrosis, kidney, tubular necrosis, edema, karyorexis, lungs, infiltration in alveoli.
