【 摘 要 】

The aim of this study was to characterize the clinical aspects of dermonecrotic loxoscelism (LDN) in horses department of Cordoba, Colombia. This study was descriptive, not probabilistic, in animals of convenience. Nine horses (Equus ferus caballus) and 2 donkeys (Equus asinus africanus) were used with LDN diagnosed clinically and histopathologically in different productions of the Department. When describing the skin lesions, these were characterized by the presence of severe necrotic dermatitis, with edema and a focal erythematous area, when detailing the injured area, a central necrotic spot and two halos around it (a medial white halo and a halo Violet) in most of the cases studied; As well as absence of neurological and systemic signs. The lesions were located in most cases at the dorsal level, followed by the rostral region, chest and penis. Histopathologically in the staining of Hematoxylin Eosin (H & E), severe piogranulomatous dermatitis was observed, with marked infiltration of polymorphonuclear cells especially neutrophils, with vacuolization of the basal layer of the epidermis and edema in the dermo-epidermal junction. The definitive diagnosis of LDN in the 11 animals studied was based on the clinical manifestations observed, the anatomopathological characteristics of the lesions and the histopathological results. The present report constitutes the first LDN report in the Department of Córdoba, since no reports were found in the consulted literature.
