An 1-year-old male Basset Hound dog was evaluated for chronic intermittent vomiting, hematemesis, and melena which had been ongoing for several months. The histopathologic examination revealed that all layers of the small intestine were thicker than normal. The lamina propria of the mucosa, including the villi, exhibited a prominent cellular infiltrate which consisted of numerous eosinophils and an increased numbers of plasma cells in addition to the normal lymphocytic component. The muscularis mucosa was invaded, and in some places disrupted, by eosinophils, which also infiltrated into the submucosa and muscularis propria. This report describes the pathological findings of a case of eosinophilic gastroenteritis (EG) in a dog
ResumoA celulite juvenil ou linfadenite granulomatosa estéril juvenil, é um distúrbio raro que acomete filhotes com idade entre três semanas a seis meses. Os sinais clínicos incluem alopecia, edema, pápulas, pústulas e crostas especialmente em pálpebras. O diagnóstico definitivo requer exames citológico e histopatológico e a terapia precoce e agressiva é preconizada, pois as cicatrizes após recuperação podem ser graves. O tratamento de escolha consiste no uso de altas doses dos glicocorticoides, como prednisona. Foram atendidos no Hospital Veterinário, três animais da espécie canina, apresentando sinais clínicos variados. Foram realizados hemograma, exame citológico das lesões de pele e dos linfonodos submandibulares. O tratamento foi instituído, utilizando-se cefalexina na dose de 22 mg/kg, duas vezes ao dia, até controle de infecção bacteriana secundária e prednisona na dose de 2mg/kg, uma vez ao dia, até regressão dos sinais clínicos. Após termino do tratamento obteve-se cura completa dos animais. O objetivo deste trabalho é relatar o caso de três animais da espécie canina, apresentando sinais clínicos variados de celulite juvenil. Palavras-chave: Celulite, canino, pústula AbstractJuvenile cellulitis or juvenile sterile granulomatous lymphadenitis is a rare disorder that affects puppies between three weeks to six months years old. Clinical signs include alopecia, edema, papules, pustules and crusts especially on eyelids. Definitive diagnosis requires cytological and histological evaluation and early and aggressive therapy is recommended, once scars after recovery can be severe .The choice treatment is the high dose of corticosteroids use such as prednisone. Three animals of canine species were attended at the Veterinary Hospital Clinical Small Animal Service presenting different clinical signs. Hemogram, skin lesions and submandibular lymph nodes cytological examination was collected and analyzed. The treatment was instituted, using cephalexin (22mg/kg, twice daily) up to control of secondary bacterial infection, and prednisone (2mg/kg, once a day) until clinical resolution. Complete cure was obtained at the end of treatment. The aim of this work is to report three clinical cases of juvenile cellulitis in dogs.
ResumoRelatam-se 15 casos de cães com abscessos prostáticos. Os animais foram submetidos a exame físico, destacando-se o toque retal associado à palpação transabdominal da próstata, seguido de hemograma, dosagem sérica de uréia, creatinina e enzimas alanino-aminotransferase e fosfatase alcalina, avaliações radiográfica e ultrassonográfica da cavidade abdominal e cultura do tecido prostático. Os animais foram submetidos a diferentes tratamentos, estes relacionados ao estado geral do animal, localização, tamanho e quantidade de abscessos prostáticos. Esta descrição reitera a importância das afecções prostáticas na clínica médica canina, sendo o exame físico detalhado e acompanhado de exames complementares específicos, particularmente raios-X e ultrassonografia, de grande valia na detecção das afecções prostáticas dos cães. As técnicas cirúrgicas empregadas são eficazes ao tratamento de abscessos prostáticos, com baixa taxa de mortalidade. Palavras-chave: Canino, próstata, prostatite aguda. AbstractFifteen cases of dogs with prostatic abscesses are reported. The animals were underwent to physical examination prioritizing the digital rectal exam with transabdominal palpation of the prostate gland followed by blood cell count, measurement of serum urea, creatinine, alanine aminotransferase and alkaline phosphatase levels, abdominal's radiographic and ultrasound exams, and culture of the prostate. The animals were underwent to different treatments being related to the animal's general state, location, size and quantity of prostatic abscesses. This description reiterates the importance of prostatic disease in canine medicine once the detailed physical examination associated with specific complementary tests, particularly x-ray and ultrasound, are valuable for the detection of dog's prostatic diseases. Surgical procedures used here are effective to the treatment of prostatic abscesses with low mortality rate.
A 10-year-old, intact male, pinscher was presented with unilateral bloodstained nasal discharge, sneezing, dyspnea, zygomatic arch deformity, submandibular lymph node increase, blindness in right eye, and exophthalmia. After clinical examination, it was found that the animal presented with upper respiratory tract dyspnea origin, possibly caused by an obstructive process. Complete blood count (CBC), ocular ultrasonography, thoracic radiographs, mandibular lymph node, and nasal sinus fine needle aspiration were performed. The right mandibular lymph node excisional biopsy was conducted and a tumor sample was obtained through the nasal fistula at hard palate. The material was processed, paraffin embedded, sectioned, and stained with hematoxylin and eosin. Immunohistochemical staining for cytokeratin (AE1/AE3), vimentin, and COX-2 was performed. After histopathological evaluation nasal carcinoma diagnosis was obtained. Chemotherapy was established with carboplatin 300 mg/m 2 intravenouslyfour cycles with intervals of 21 days-and firocoxib 5 mg/kg orally every 24 hours for 7 months. After 7 months the treatment started, the animal presented with ataxia, vocalization, hyperesthesia, and anorexia. Due the clinical condition presented, the animal owner opted for performing euthanasia. The chemotherapy protocol was effective causing the disease stagnation, minimizing the clinical signs, and extending patient survival and quality of life.
An 7-year-old male German shepherd dog not neutered was attended presenting several cutaneous nodules ranging from 0.5-3 cm in diameter at least a one year history, located mainly in thoracic and pelvic limbs, with progressive weight loss over two months. Fine needle aspiration biopsy and pelvic and thoracic limbs nodules excision biopsy were performed. After histopathological diagnosis, nodular dermatofibrosis diagnosis was determined and abdominal ultrasound was performed for possible renal cysts evaluation. The animal received treatment to control secondary bacterial infection. It is necessary to carry out histopathological examination and ultraosund to identify possible renal cysts and for definitive diagnosis. There is no specific treatment for nodular dermatofibrosis.
