Identificación de patrones histopatológicos en perros con dermatopatías no neoplásicas atendidos en veterinaria Anubis.

Abstract

The histopathological pattern constitutes an effective tool for a correct knowledge of the degree of lesion present in the skin of canines. The research was developed with the objective of identifying histopathological patterns of cutaneous inflammation in dogs with non-neoplastic dermatopathies treated in the veterinary clinic Anubis, Machala, province of El Oro, in the period from November 2023 to January 2024, for this purpose, 22 canines of different breeds were sampled and the techniques of skin scraping, imprinting, Cook's tape were applied, and after a lesion was detected, a punch biopsy was performed. The association between the breeds and the causal agents of dermatopathologies with the histopathological patterns found was established by means of multiple correspondence analysis, where a greater closeness of the categories of the variables evidences a greater predilection to suffer the cutaneous pathology. Pyodermas and dermatomycosis were the main dermatopathologies found in the canines studied and the Doberman Pincher, American Bullyng, French Poodle, Pitbull and Chihuahua breeds presented a greater predisposition to suffer the DPSP histopathological pattern, mostly associated to adult animals. The causative agents Bacteria (Pyodermas) and Fungi (Malassezia and Dermatophytes) presented the highest frequency of involvement. The histopathological pattern DPSP was found to be highly associated with the presence of Pyodermas. Three histopathological patterns of non-neoplastic dermatopathies were found in the period studied, including DPSP, PFF and DND. The histopathologic pattern of non-neoplastic dermatopathies with the highest frequency of occurrence in the sample studied was superficial and deep perivascular dermatitis.
