Abstract
CASE DESCRIPTION A 5.5-year-old 0.929-kg spayed female domestic ferret (Mustela putorius furo) underwent serial abdominal ultrasonographic and clinicopathologic examinations after multiple renal cysts were detected bilaterally during a routine examination. CLINICAL FINDINGS The ferret was apparently healthy at the start of the monitoring period and had no clinical signs for > 20 months. Four months after the initial examination, the largest cyst became increasingly mineralized; 17 months after detection, it had increased in size and become amorphous, and the ferret's plasma BUN concentration was mildly high. Within 21 months after the first visit, a nodule was detectable, and hydronephrosis developed in the kidney with the largest cyst. Findings for fine-needle aspirates from the nodule were consistent with renal carcinoma. TREATMENT AND OUTCOME Contrast-enhanced CT revealed severe unilateral nephromegaly with no contrast uptake in the affected ureter. Following surgical removal of the affected kidney, histologic examination identified renal adenocarcinoma replacing the entire renal cortex and medulla. The ferret was euthanized postoperatively because of declining condition. On necropsy, metastasis to a mesenteric lymph node was identified; comorbidities included 2 other neoplasms and acute, severe injury of the contralateral kidney. CLINICAL RELEVANCE Neoplastic transformation of a renal cyst was suspected in the ferret of this report on the basis of observed ultrasonographic changes over time and extensive infiltration of the neoplasm throughout the affected kidney. Renal cysts are linked to renal neoplasia in other species, and the findings for this patient supported the need for periodic monitoring of renal cysts in ferrets.

Abstract
Humans are not the only species to spontaneously develop metastatic cancer as cases of metastasis have been reported in a wide range of animals, including dinosaurs. Mouse models have been an invaluable tool in experimental and clinical metastasis research, with the use of genetically-engineered mouse models that spontaneously develop metastasis or ectopic/orthotopic transplantation of tumour cells to wildtype or immunodeficient mice being responsible for many key advances in our understanding of metastasis. However, are there other species that can also be relevant models? Similarities to humans in terms of environmental exposures, life-span, genetics, histopathology and available therapeutics are all factors that can be considered when looking at species other than the laboratory mouse. This review will explore the occurrence of metastasis in multiple species from a variety of domestic, captive and free-living veterinary cases to assist in identifying potential alternative experimental and clinical research models relevant to humans.

Abstract
14-3-3σ is a protein expressed in many epithelial tissues associated with essential cell functions, including cell-cycle control, apoptosis, and cytoskeletal integrity. There is a paucity of knowledge of the tumorigenesis of canine renal cell carcinomas (RCCs), and the histological origin of this tumor has not been established. This study analyzed the expression of 14-3-3σ, Ki-67, cytokeratins, and vimentin in 40 canine RCCs. Aberrant expression of 14-3-3σ was demonstrated in 15 (38%) cases and was associated with a significantly shorter survival time ( P < .002). In contrast to canine RCC, normal kidney did not express 14-3-3σ. The Ki-67 proliferation index did not show utility as a prognostic factor. The distal convoluted tubular epithelium in normal kidneys coexpressed cytokeratins and vimentin, and thus maintenance of this coexpression pattern in canine RCC suggests that most tumors arise from the distal segment of the nephron. These results suggest that 14-3-3σ is a potential negative prognostic factor and a possible therapeutic target.

Abstract
OBJECTIVE Being confronted with a case series of renal neoplasia in several horses which was in striking divergence to literature data, we recognized the need of a retrospective study to assess the presence of renal neoplasms in horses. MATERIAL AND METHODS Anamnestic animal data, necropsy findings and results of histological and immunohistochemical examinations from 2010 through 2015 were collected and evaluated regarding renal neoplasia. RESULTS Data from postmortem examinations of 1069 horses revealed 20 horses with renal tumors constituting a prevalence of 1.87 %. Primary renal neoplasms built the majority of cases (n = 15; 75 % of total renal neoplasms) and comprised nine renal carcinomas, four renal adenomas, one renal neuroendocrine tumor and a single nephroblastoma. Among the five secondary renal neoplasms lymphosarcoma was most common (3/5). Remaining metastatic tumors comprised one melanoma and one hemangiosarcoma. No breed or sex predilections were noticeable. Except for the case of nephroblastoma in a stillborn foal, all horses presenting with renal tumors were more than 10 years of age, often older than 20 years. Anamnestic data and clinical symptoms were inconclusive and not assigned to renal disease in most cases. Merely one horse with renal carcinoma presented with renal insufficiency and two horses showed signs of shock due to severe bleeding after tumor capsule rupture in renal carcinoma. CONCLUSION AND CLINICAL RELEVANCE Renal tumors occur more often than anticipated, especially in older horses. Contradictorily to the literature, primary renal tumors significantly outnumbered secondary neoplasms in this study.

Abstract
Resumo: Numa pesquisa em abatedouros a procura de lesões em bovinos, realizada de janeiro de 2011 a julho de 2014, 544 foram encontradas, das quais 65 eram neoplasmas. Quarenta e dois porcento desses tumores eram de origem mesenquimal; 37% eram epiteliais; 14,5% eram derivados da crista neural; 5% eram tumores do cordão sexual; e 1,5 eram tumores originários do sistema nervoso periférico. O tumor mais frequentemente encontrado foi o linfoma (28% de todos os tumores), a maioria dos casos como parte do complexo leucose bovina enzoótica. O carcinoma de células escamosas foi o segundo tumor mais frequente (15% de todos os tumores). É chamada a atenção para a frequência desses tumores e para a sua importância no diagnóstico diferencial no abatedouro frigorífico entre eles e outras lesões importantes, incluindo as lesões granulomatosas da tuberculose. Houve uma ocorrência significativa do feocromocitoma adrenal (13% de todos os tumores). Papilomatose representou apenas 3% de todos os tumores. Como papilomas são comuns em bovinos, seu baixo número nesse estudo pode ser explicado pelo fato de que eles não são usualmente diagnosticados no exame post mortem (quando o couro já foi retirado da carcaça), mas sim no exame ante mortem, como ocorreu na maioria dos casos deste estudo. Tumores encontrados com menor frequência (cada um perfazendo entre 1.5 e 3% de todos os tumores) incluíram adenocarcinoma apócrino misto da cauda, adenocarcinoma mamário, adenocarcinoma uterino, carcinoma de células renais, fibroma interdigital, hemangiossarcoma, leiomioma uterino, lipoma, lipossarcoma, mesotelioma, neurofibroma, tumor de células da granulosa, tumor estromal gastrointestinal, tumores hepáticos, tumores melanocíticos, e tumores pulmonares primários. Pretende-se que os resultados dessa pesquisa possam ajudar na identificação das lesões na inspeção oficial em matadouros frigoríficos.

Abstract
Canine renal cell carcinomas (RCCs) are uncommon aggressive tumors that occur mainly in middle-aged male dogs. Their histologic classification bears no relationship with prognosis, and little information is available concerning their immunohistochemical properties. In this retrospective study, formalin-fixed, paraffin-embedded tissues from 13 canine RCCs were retrieved from the archives, classified histologically, and evaluated immunohistochemically. The dogs were 7 males and 6 females (1 spayed) of 10 different breeds, averaging 8 years in age. The tumors were classified as papillary, tubulopapillary, papillary–cystic, solid, or sarcomatoid. All 13 tumors were immunohistochemically positive for uromodulin, 12 for c-KIT, 11 for vimentin, 9 for wide-spectrum-screening cytokeratins, 7 for cytokeratins AE1/AE3 and carcinoembryonic antigen, 4 for cytokeratins CAM 5.2, and 3 for CD10. All 3 solid RCCs expressed vimentin, c-KIT, and carcinoembryonic antigen and were negative for cytokeratins. All 7 papillary and tubulopapillary tumors expressed vimentin; 6 (86%), cytokeratins; and 6 (86%), c-KIT. Both papillary–cystic RCCs were positive for cytokeratins and c-KIT and negative for vimentin. These results indicate that the different histologic types of RCC have characteristic immunohistochemical profiles and that c-KIT may be involved in the pathogenesis of canine RCC.

Abstract
Thirty-eight cases of renal tubular cell neoplasms were diagnosed in 184 captive, adult (>1-year-old), black-footed ferrets (Mustela nigripes) examined from 1985 to 1996. This prevalence (20.7%) is one of the highest reported for this neoplasm in a population of animals. These tumors rarely metastasized (1/38), and usually were incidental postmortem findings, associated clinical disease being present in only 3 (8%) of the 38 cases. The prevalence of renal tubular cell neoplasms found at postmortem examination increased linearly with age, up to 67% in ferrets >8 years old. Both males (prevalence = 19%) and females (prevalence = 24%) were affected. Multiple renal tumors were common, and seven ferrets (18.4% of affected animals) had bilateral tumors. The cause of this neoplastic syndrome could not be determined. Since most of the animals affected by this condition were in their postreproductive years of life, the impact of this neoplastic syndrome on the captive propagation of this species is negligible.

Abstract
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 firmes. Na região do hilo e no lobo apical esquerdo dos pulmões havia aumento de volume, com 11 × 7cm de extensão, de superfície irregular e bem vascularizada, esbranquiçada e com áreas de consistência ora firmes, ora friáveis. No lobo apical direito também havia um nódulo com 1cm de diâmetro, firme e esbranquiçado. Secções histológicas dos pulmões e dos rins foram coradas pela hematoxilina-eosina, Masson e Van Gieson. Foi detectada positividade, pela imuno-histoquímica, para a vimentina e actina alfa de músculo liso. Não houve imunomarcação para citoqueratinas 1, 5, 10, 14, 8 e 7, proteína S100 e para CD68. Com base nos achados anatomopatológicos e imuno-histoquímicos foi firmado o diagnóstico de leiomiossarcoma pulmonar e renal, sem, no entanto, definir o sítio primário da neoplasia.
