| A case of mammary carcinosarcoma is reported in a 13-year-old, mixed breed female cat, which was not spayed and had not received contraceptives. The patient presented extensive and coalescent nodules in all mammary glands. Based on the histological and immunohistochemical findings, the diagnosis of mammary carcinosarcoma was confirmed. |

| Mitotic index, nuclear diameter, number of nucleolar organizing regions, and Ki-67 expression, in hair follicle tumors of 82 dogs were evaluated. Tissue specimens were used to prepare sections for histological staining for number of nucleolar organizing region and immunohistochemical staining for Ki-67. Tumors were classified as trichoblastoma (n=32), benign trichoepithelioma (n=30), pilomatricoma (n=7), malignant trichoepithelioma (n=6), infundibular keratinizing acanthoma (n=5), and tricholemmoma (n=2). Head, dorsum, and limbs were the most affected sites. Malignant trichoepithelioma presented significantly higher mitotic index, number of nucleolar organizing regions and Ki-67 expression. Regarding benign neoplasms, trichoblastoma presented significantly... |

| 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... |

| Flow cytometric analysis of DNA content was performed on 28 samples of canine mammary tumors. Nine of them were benign and 19 were malignant. All benign tumors and 11 malignant tumors (57.9%) were diploid (P<0.05). Form the aneuploid tumors, five (26.3%) were hyperdiploid, one (5.3%) hypodiploid, one (5.3%) near triploid and one (5.3%) multiploid. The analysis of the expression of the markers PR and CD31 revealed a significant difference between diploid and aneuploid tumors (P<0.05). The immunoreactivity of PR was higher in diploid tumors, while the immunoreactivity of CD31 was stronger in aneuploid tumors. No difference between the markers MIB-1, c-erbB2, p53 and Cyclin D1 was observed (P>0.05). Using the flow cytometry analysis and... |

| ABSTRACT Intestinal carcinomas are rare in dogs. The prognosis and survival time are dependent of the histological type, the invasion of the intestinal wall by the malignant cells and the ability of primary neoplasm to produce metastasis. This study reports a case of a Yorkshire dog that developed a rectal tubulopapillary adenocarcinoma progressing to a peritoneal carcinomatosis and multiple metastasis in large intestines, bladder, kidney, iliac lymph node, liver and lungs, six months after transanal surgical resection of the primary rectal neoplasm. Clinical, surgical, pathological and immunophenotypic findings are described. COX-2 imunohistochemical score was higher in hepatic metastasis (score 9) than in the primary tumour (score 6), and the growth... |

| Uma chimpanzé de 22 anos de idade foi necropsiada com histórico clínico de anorexia, vômitos freqüentes e desidratação conseqüentes à gastrite iatrogênica. Macroscopicamente, o útero apresentava-se aumentado de volume, com o lúmen totalmente ocluído por nódulos firmes, esbranquiçados e coalescentes que se estendiam para o miométrio. Histologicamente, os nódulos eram constituídos por leiomiócitos bem diferenciados dispostos em várias direções e com coloração característica pelo tricrômio de Gomori e Masson. Pela imunoistoquímica, as células neoplásicas apresentavam marcação forte e difusa de receptores para progesterona e estrógeno, assim como de actina alfa de músculo liso. Algumas células neoplásicas e o estroma apresentavam marcação para vimentina e... |

| Twenty BALB/c mice were inoculated with cell suspension of Ehrlich tumor. Ten mice were inoculated in the cushion plant (solid form) and the other 10 in the peritoneum (ascitic form). Animals were euthanized on different times (7 and 14 days). Cytological and histological slides, immunohistochemical (PCNA) analysis and NORs silver impregnation technique were performed. The results showed more proliferation on the 7th day in the ascitic form and on 14th day in the solid form, using both analyses (PCNA and AgNORs). The alterations observed in the Ehrlich tumors proliferation activity suggested that the growth curve is different between ascitic and solid forms. In the first one, the proliferation peak occurs on the seventh day and in the solid tumor the... |

| Estudou-se atividade antineoplásica de um produto natural isolado de Alomia myriadenia (miriadenolídeo) no modelo do tumor de Ehrlich em camundongos. Dezoito fêmeas de camundongo Swiss foram inoculadas com 2x10(7) células viáveis de tumor de Ehrlich via intraperitoneal (0,3ml) e posteriormente distribuídas aleatoriamente em três grupos que receberam: grupo I (controle) - 0,3ml de solução de Hanks; grupo II - 31µg/kg de miriadenolídeo; e grupo III - 139µg/kg de miriadenolídeo. No oitavo dia de experimento, foram realizados exames hematológicos e perfil protéico sérico eletroforético. Coletou-se todo o líquido ascítico para avaliação do volume, aparência, pH, contagem de células viáveis e inviáveis, realização de esfregaços para contagem de células claras e... |

| Adult male mongrel dogs were subcutaneously transplanted with the canine transmissible venereal tumor (TVT) on the hypogastric region. Twelve specimens of tumors were collected, half during the proliferative phase and the other half during the regressive phase. Fragments of the tumor were fixed in 10% buffered formalin and routinely processed for light microscopy. Sections of 4µm were stained by Schorr or AgNOR or either immunostained for MIB1 (Ki67). Schorr stain, AgNOR and MIB1 showed an increased proliferative activity through mitotic index, nuclear argyrophilic protein stain and cycling tumoral cells in the growing tumors, respectively. All of the three cell proliferation markers were able to distinguish the TVT in both evolution phases. MIB1... |

| The authors describe their experience with an automated immunohistochemical system applied to canine tissue samples. Twenty human cellular markers specific monoclonal and polyclonal antibodies and two different antigen retrieval methods were used in normal and neoplastic breast tissue, as well as skin samples obtained from female dogs of pure and mixed breeds. The antibodies tested were the most frequently used in human and veterinary medicine studies, employed with diagnostic purposes in breast pathology, as well as in cancer research. Most of them may be used to study other normal and abnormal tissues and included cytokeratins, progesterone receptor, c-erbB2, p53, MIB-1, PCNA, EMA, vimentin, desmin, alpha-actin, S-100, pan-cadherin, and E-cadherin.

| Three methods for the analysis of cell proliferation, mitotic index/10 high-power fields (10 HPF), mitotic index/four sets of 10 HPF (40 HPF), and MIB-1 index were evaluated in a series of canine mammary gland tumors, as well as the possible correlation between them. Fifty-six canine mammary gland tumors, including 23 benign and 33 malignant, were studied. In addition, the prognostic impact of mitotic index/10 HPF, and histological malignancy grade were evaluated in 17 malignant tumors, being seven ductal and 10 metaplastic carcinomas. The three methods used to evaluate cell proliferation were correlated with the prognostic impact of mitotic index/10 HPF and histological malignancy grade. The results showed a strong association between mitotic figure... |
