The clinical examination and anatomopathological characterization of the lesions were performed, with similar manifestations in both animals, which consisted of the presence of edema and a focal erythematous area, when detailing the injured area, a central necrotic point and two halos were observed, a medial white halo and a more external violet halo; As well as absence of neurological and systemic signs. The diagnosis was made based on the clinical characteristics in the animal and anatomopathological analysis of the lesions, which are characteristic in this type of poisonous accident by spiders of the genus Loxosceles.
