Canine facial eosinophilic furunculosis in a dog

Canine facial eosinophilic furunculosis (FEF) is a hyperacute dermatopathy especially of the nasal bridge of dogs and is probably associated with type I hypersensitivity secondary to arthropod bites. The aim of this study is to report on a FEF case in a four-year-old female free-roaming mixed-breed dog showing papules on the nasal bridge that evolved to an ulcerated plaque. No other clinical, hematological, or biochemical alterations were detected. Cytology revealed eosinophilic and neutrophilic inflammation associated with bacterial infection. Punch biopsies were obtained for histopathological and microbiological analysis. Histopathology revealed marked, acute, multifocal to coalescent granulomatous eosinophilic furunculosis, and mild, acute, multifocal eosinophilic folliculitis. Microbiology revealed growth of coagulase-positive Staphylococcus sp. Clinical and histopathological findings were suggestive of facial eosinophilic folliculitis and furunculosis. Complete remission of the lesions was obtained after treatment. This condition is hyperacute, progressive, with a papular and erosive to ulcerative pattern, good prognosis, and its development is linked to arthropod bites. Furthermore, anti-inflammatory therapy is effective in treating the disease.(AU)

Biometry of adrenal glands of mixed-breed dogs

Background: Differences of the size of the adrenal glands, in healthy dogs or in endocrinopathies, undermine correct diagnosis of endocrine disorders and evaluations of the adrenal cortex in relation to its size and possible correlation with endocrinopathies are rare. The aim of the present study was to perform measurements of the length, width, thickness and weight of the adrenal glands of young, adult and elderly mixed-breed dogs and correlate them with the age, sex and weight of animals. In addition, the areas occupied by the zona glomerulosa, zona fasciculata, and zona reticularis of the adrenal cortex were measured in order to establish a microscopic biometric pattern. Material, Methods & Results: The right and left adrenal glands of 12 young (six females and six males), 12 adults (six females and six males), and 12 elderly (six females and six males), all mongrels, derived from routine and necropsied in the Animal Pathology Sector of the Veterinary Hospital of the Federal University of Espírito Santo (HOVET-UFES) were weighed and the length, width, and thickness were measured. For the microscopic measurement of the adrenal cortex, 10 randomly selected samples were submitted to routine histological processing and the microscope slides were observed under a light microscope at 5× and 10× objectives, photodocumented and measurements were obtained from a random portion of the adrenal cortex and the zones composing the cortex were measured in triplicate with the aid of the computerized image analysis software. The left adrenal showed a greater average length than the right adrenal in young, adult, and elderly dogs. The size of the glands in the young and adult dogs is not influenced by the sex of the animals, but in older dogs the females had a greater mean...
