| Realizou-se anastomose cólon-trígono vesical em 12 cães adultos (cinco machos e sete fêmeas), sem raça definida e clinicamente normais. Todos os animais mantiveram a continência urinária imediatamente após a cirurgia. Amostras da região de transição cólon-trígono vesical foram colhidas aos 30 e 60 dias após a cirurgia para exames histopatológicos. Observou-se infiltrado inflamatório mononuclear na região de anastomose com invasão do epitélio de transição da bexiga sobre a mucosa do fragmento intestinal. A técnica mostrou-se simples e eficiente para a reparação da bexiga, com o cólon funcionando como substituto da bexiga, preservando as funções renal e vesical. |

| ABSTRACT Electrochemotherapy is a local anticancer treatment in which non-permeant chemotherapeutic drugs are associated with electric pulses of well-established parameters. The electric pulses cause pores to open on the plasma membrane and facilitate drug transport, enhancing cytotoxicity and reducing side effects. Assessment of electrochemotherapy effects on Ehrlich solid tumor development in this work aims to evaluate in vivo usage of the electroporator device developed by the Department of Electrical Engineering of Engineering School of UFMG. Therefore, 40 Swiss mice were inoculated with Ehrlich tumor cells, and developed the tumor in solid form. After 21 days, mice were subjected to specific treatment protocols (control, bleomycin, electric pulses and... |

| ABSTRACT Metronomic chemotherapy consists of an anticancer modality treatment. It is applicable in patients at an advanced stage, with the objective of increasing overall survival. The aim of this study was to report an anal sac apocrine carcinoma case in a dog with lymph node metastasis treated with metronomic chemotherapy sequential to surgery and conventional chemotherapy using gemcitabine and carboplatin. Metronomic chemotherapy was associated with cyclooxygenase-2 (COX-2) inhibitors, due to strong tumor COX-2 immunohistochemistry expression. Metronomic chemotherapy was initiated with cyclophosphamide, but it was replaced by lomustine, also in metronomic dosage, due to adverse effects. Treatment showed effectiveness, since the patient's overall... |

| A 3-year-old female Pinscher dog was presented with a history of lameness and pain in hind limbs for one week which acutely progressed to non-ambulatory paraparesis. The dog had been apathetic and anorexic during the six days prior to presentation. The neurological findings were compatible with upper motor neuron signs to the left hind limb due to a spinal cord compressive mass on the twelfth thoracic vertebral body. On the other hand, signs of lower motor neurons to the right hind limb were due to a mass with a pathological fracture in the right proximal femur, compressing the sciatic nerve. A histopathological analysis of all organs revealedthe proliferation of endothelial cells showingin filtrative growth and organization into vascular structures with a... |

| ABSTRACT Feline Injection Site-Associated Sarcoma (FISS) is a neoplasm that implies in reduction of quality of life and overall survival in feline patients. A retrospective study of 13 cases of FISS was conducted to evaluate the efficacy of surgical treatment associated to chemotherapy with doxorubicin or carboplatin. Local recurrence occurred in all patients. Patients treated with surgery and chemotherapy presented a longer overall survival and disease-free interval when compared to those that solely received surgical treatment, although no statistical significance was observed (p= 0.3360 and 0.7506, respectively). Surgery remains as the main option for FISS treatment. Further prospective studies with larger samples are warranted to investigate the... |

| ABSTRACT The aim of this report is to describe the first histopathological, immunohistochemical, and clinical characteristics of a feline glycogen-rich clear cell carcinoma (GRCCC). A Persian queen was admitted with mammary gland tumors and underwent radical unilateral mastectomy. Overall survival was considered 33 days and death was due to clinical evolution of the disease. Microscopic evaluation demonstrated epithelial cells arranged in a predominantly solid pattern, tumor cells presented an ample, granular, and foamy clear cytoplasm, and moderate cellular pleomorfism. The presence of cytoplasmatic glycogen was confirmed through diastase digestion followed by PAS staining. Histopathological and histochemical findings lead to the diagnosis of GRCCC with... |

| Este relato descreve um caso de leiomiossarcoma pulmonar e renal em cão da raça Husky Siberiano, macho, de nove anos de idade e com histórico de emagrecimento progressivo há mais de três meses. Ao exame clínico, o animal apresentava palidez discreta das mucosas e dor intensa à palpação abdominal, além de aumento de volume acentuado dos rins. No hemograma, foi evidenciada anemia discreta e na urinálise foram observados isostenúria e grumos de células do epitélio renal. Os níveis plasmáticos de uréia e creatinina estavam dentro dos limites considerados normais. O animal foi sacrificado após a confirmação de neoplasia renal bilateral por laparotomia exploratória. À necropsia, os rins apresentavam vários nódulos de 0,5 a 4cm de diâmetro, esbranquiçados e... |

| ABSTRACT In spite of the many available protocols, the use of chemotherapy for the management of canine mast cell tumours (MCT) remains empirical, and there is lack of criteria for the choice of protocol and definition of patients who may benefit from treatment. The objective of this study was to evaluate the outcome of dogs with MCT after adjuvant chemotherapy according to the risk of recurrence or metastasis proposed on the literature. This prospective study included 89 followed up dogs with prognosis assesment including clinical, histological, immunohistochemical and genetic features of canine MCT. Patients were grouped according to risk of recurrence and metastasis and recommended treatment with lomustine followed by chlorambucil if considered at... |

| Fine needle aspiration (FNA) associated with the cytological diagnosis mast cell tumor is a widely employed technique in human medicine, but it is still underused in veterinary medicine. The aim of this study was to demonstrate the efficacy of FNA technique for the diagnosis of mast cell tumors in dogs. Over one year period all dogs referred to the Veterinary Hospital of the Universidade Federal de Minas Gerais with tumor-like formations of the skin were submitted to FNA. In order to detect metastasis, both skin lesions and the regional lymph nodes were subjected to FNA. After surgical removal of the lesions, histological examination indicated a complete agreement with the cytological diagnosis. In conclusion, FNA technique is a good choice for diagnosis... |

| ABSTRACT The aim of this study was to relate the serum concentration IL-6, IGF-1, leptin and estrogen in non-castrated bitches with or without overweight and early stage mammary carcinomas. Forty-three bitches were divided into four groups, two groups without mammary carcinomas with and without overweight, and two groups with mammary carcinomas with and without overweight. Overweight bitches, with or without mammary carcinomas, were statistically different from bitches by ideal weight, in relation to ECC, IMCC and body fat percentages (P< 0.0001). There was a positive correlation between ECC and IMCC (P< 0.0001), ECC and % GC (P< 0.0001), and IMCC and % GC (P< 0.0001). A positive correlation was found between serum leptin and IL-6 (P= 0.0451)... |

| Descrevem-se os achados anatomoclínicos e imunoistoquímicos dos tumores da bainha de nervos periféricos em três cães atendidos em hospital. Os animais apresentavam sintomatologia variável de acordo com a localização do tumor. À microscopia, as neoplasias eram invasivas e constituídas por células pleomórficas e anaplásicas que variavam de poligonais a fusiformes, arranjadas em padrão sólido difuso, por vezes em paliçada. Foi firmado o diagnóstico de tumor da bainha de nervos periféricos nos três casos. |
