| A case of urethral carcinoma in 15-year-old mongrel male dog is described. Signs of dysuria, urethral obstruction, tenesmus, pain and cough were mentioned. Clinically, the animal was undernourished and showed signs of pain and bladder repletion during the palpation of the abdominal region. Other complementary exams were made such as routine urinalyses, X-ray, ultrassonography and measurement of blood urea and creatinine. Macroscopically, the mucous membrane of pelvic urethra was somewhat irregular, due to the presence of several small white irregular and ulcerated nodules of imprecise boundaries. Similar nodules were found in the lungs and heart. Histologically, transitional cell carcinoma of urethra with metastasis to lung and heart was detected. |

| Los perros, al igual que los humanos, son las únicas especies que desarrollan cáncer de próstata de forma natural y con relativa frecuencia. El carcinoma prostático (CP) es una neoplasia que se origina en el epitelio glandular de la próstata. En perros, su incidencia varía entre 0.29 y 0.6% y no hay evidencia de factores que favorezcan su desarrollo; mientras que, en humanos, se ha asociado, entre otras causas, con la genética y con dietas ricas en grasa. En perros, histológicamente se han descrito cuatro patrones: tubular, micropapilar, cribiforme y plano, de los cuales el tubular es el más frecuente. Este tipo de tumores frecuentemente hace metástasis a linfonodos regionales, pulmones y hueso. El presente caso clínico corresponde a un perro de 11 años,... |

| Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants that can be present at high levels as mixtures in polluted aquatic environments. Many PAHs are potent mutagens and several are well-known carcinogens. Despite numerous studies on individual compounds, little is known about the toxicity of PAHs mixtures that are encountered in environmental situations. In the present work, zebrafish were continuously fed from 5 days post-fertilisation to 14 months post-fertilisation (mpf) with a diet spiked with fractions of either pyrolytic (PY), petrogenic light oil (LO), or petrogenic heavy oil (HO) origin at three concentrations. A decrease in survival was identified after 3 mpf in fish fed with the highest concentration of HO or LO, but not for PY. All... |

| Several investigators have identified Epstein-Barr virus (EBV) particles in breast carcinomas, a fact that supports a role for EBV in mammary tumorigenesis. The possible mechanism involved in this process is not clear. The present study was carried out in an attempt to determine whether there is a relationship between latent infection with EBV and p53 and p63 expression in breast carcinomas. Immunohistochemistry developed with 3.3-diaminobenzidine tetrahydrochloride was performed in 85 formalin-fixed paraffin-embedded breast carcinomas using anti-EBV EBNA-1, anti-p63, anti-p53, anti-estrogen receptor (ER) and anti-progesterone receptor (PR) antibodies. The cases were selected to represent each of the various histologic types: intraductal carcinoma (N =... |

| Cell interactions with extracellular matrices are important to pathological changes that occur during cell transformation and tumorigenesis. Several extracellular matrix proteins including fibronectin, thrombospondin-1, laminin, SPARC, and osteopontin have been suggested to modulate tumor phenotype by affecting cell migration, survival, or angiogenesis. Likewise, proteases including the matrix metalloproteinases (MMPs) are understood to not only facilitate migration of cells by degradation of matrices, but also to affect tumor formation and growth. We have recently demonstrated an in vivo role for the RGD-containing protein, osteopontin, during tumor progression, and found evidence for distinct functions in the host versus the tumor cells. Because of the... |

| O carcinoma epidermoide é uma neoplasia maligna, invasiva proveniente dos queratinócitos, que está relacionada com fatores carcinogênicos, principalmente a radiação solar. Os animais mais predispostos são os de pelagem clara e idosos. O presente trabalho objetivou relatar a ocorrência de carcinoma epidermoide em gatos na clínica veterinária da USS, no período de janeiro de 2010 a janeiro de 2014. Foram analisadas 229 fichas, observando-se dados como idade, pelagem, sexo e raça. Gatos despigmentados (22,2%), idosos (44,4%), machos (55,5%), SRD (100%) e lesões em aurícula (100%). No entanto, ao cruzar dados de todos os animais atendidos no período citado, observou-se que somente a faixa etária apresentou-se estatisticamente diferente (p>0.05). Dentre os... |

| The exact pathogenesis of gallbladder adenomyomatosis is still lacking and some controversies over its diagnosis and treatment exist. Originally recognized as a precancerous lesion, adenomyomatosis is currently recognized by recent studies as a benign alteration of the gallbladder that is often associated with cholecystitis and cholecystolithiasis. Gallbladder carcinoma is an extremely malignant disease with a 5-year survival rate of less than 5%. Therefore, it is important to diagnose, differentiate, and confirm the relationship between adenomyomatosis and early-stage gallbladder carcinoma. However, the early clinical symptoms of adenomyomatosis are extremely similar to those of gallbladder stones and cholecystitis, increasing the difficulty to identify... |
