Background: Toxic agents are chemical substances or physical agents that, when interacting with living organisms, cause harmful effects. For animals, toxic products include those intended to combat endo and ectoparasites, rodenticide products, and heavy metals. Minerals and dietary additives, even if essential to the animal, can become toxic agents, among which sodium chloride, copper, urea, and ionophore antibiotics stand out. This study aimed to survey the diagnoses of accidental poisoning in ruminants over 65 years as recorded in the files of the Pathological Anatomy Sector of the Federal Rural University of Rio de Janeiro. Materials, Methods & Results: The diagnoses of poisoning by ticks, rodenticides, heavy metals, macro and micronutrients, and dietary additives in ruminants were made based on the association of epidemiological, clinical, and anatomopathological findings and, in some cases, by histochemical (rubeanic acid and Masson trichrome) and toxicological examinations. A review of data recorded over 65 years identified 372 poisonings in ruminants. Of these, 85.5% (318/372) were in bovine species and 14.5% (54/372) in goats, sheep, and buffaloes. The outbreak of poisoning by organophosphates resulted in the death of 16 cattle that ingested contaminated broken rice and corn. The spraying of this product on the bags was intended to control insects. Intoxication due to excessive administration of abamectin resulted in the intoxication of 16 calves, in two distinct farms. Toxicosis caused by coumarin derivatives resulted in the death of six cattle after accidental ingestion of these rodenticides near the pens. Arsenic poisoning occurred due to ingestion of ant poison, available in bone meal and a mineral salt, through baths with arsenic-based ticks, or in cases later confirmed by toxicological analysis, resulting in the death of 109 cattle. Sodium chloride toxicosis resulted in the death of 10 sheep...

Background: Ionophore antibiotics are food additives with coccidiostatic or antimicrobial action; they are also used as growth promoters, ruminal pH regulators, volatile fatty acid molar modifiers, and methanogenesis reducers. However, these compounds have the potential to cause microbial resistance, in addition to the risk of intoxication. Ionophore poisoning may be caused by excessive intake, sensitivity of certain animal species, and concomitant use with other drugs. In Brazil, cases of ionophore poisoning in buffalos are rare. This study aims to describe the epidemiological, clinical, and pathological findings of lasalocid poisoning in buffalo calves. Case: A visit was made to a farm in the municipality of Mojú, Pará state to care for Murrah buffalo calves. After weaning, the buffalos were grazed in paddocks with Panicum spp., and received a supplement of mineral, protein, and vitamin. This supplement contained, per kg, 250 g PB, 50 g Ca, 20 g P, 8 g S, 39 g Na, 20 mg Co, 557 mg Cu, 200 mg Fe, 12.4 mg Se, 2040 mg Zn, 0.19 mg biotin, 26750 IU of vitamin A, 4175 IU of vitamin D, 155 IU of vitamin E and 300 mg/kg of lasalocid. The product was made available to all calves, at 1-2 g/kg body weight (BW), according to the manufacturer's recommendations. Older calves were raised together with those less than 30 days old; as a result, the older calves tended to eat more, which could lead to a supplementation consumption of more than 1 kg body weight per animal per day. It was reported that between 40 and 60 days after the introduction of this supplement, 16 calves fell ill and died due to apathy, motor instability, tremors, and distended neck. The herd had a mortality rate of 33.3%. Two calves underwent a necroscopic examination at the Pathology Section of the Veterinary Institute of the Federal University of Pará. Macroscopic examination revealed extensive pale areas in the skeletal muscles, myocardium, and tongue. Fragments of these muscles and various organs were collected, fixed in 10% buffered formalin, processed according to the routine histological technique, and stained with hematoxylin-eosin and Masson's trichrome stain. Microscopic examination of the histologic samples revealed foci of muscle atrophy and necrosis characterized by an increase in cytoplasmic eosinophilia associated with the loss of stretch marks, and hyperchromatic nuclei that were displaced to the periphery. The necrosis of the muscle fibers was highlighted by Masson's trichrome staining. Discussion: The diagnosis of lasalocid poisoning in buffalo calves was based on epidemiological data, clinical findings, results of macroscopic and histopathological examination, and based on the estimated ionophore intake, obtained directly from the supplement label and by the calf's handler. Based on the absence of stratification of the calves by similarity of age and because the buffalo calves older than 30 days could eat more than 1 kg of the supplement (containing 300 mg/kg of lasalocid), it was possible to estimate the intake of lasalocid per kg CP (body weight). Therefore, the intake of lasalocid by a 70-kg buffalo calf in approximately 90 days and daily supplement consumption between 1 and 1.5 kg would be between 4.2 and 6.4 mg/kg of body weight. This report reinforces that notion that buffalo calves should never ingest ionophores; however, if necessary, strict protocols must be followed to avoid poisoning in these animals. This study highlighted the fact that stratification of buffaloes by different age groups during feeding became a risk factor that allowed greater consumption by older animals; this led to the estimated consumption of 4.2-6.4 mg/kg of lasalocid.

Background: Angiolipoma is a benign tumor composed of endothelial cells and mature adipocytes. Tumors reported indomestic species include two variants; infiltrative or non-infiltrative. Bitches and intact males seem predisposed. Thismesenchyme tumor is commonly mistaken with lipoma due to its soft texture and subcutaneous site and often requireshistopathology to confirm its diagnosis. Microscopic examination also enables the evaluation of surgical margins and ruleout possible infiltrative sites. Complete surgical excision is usually curative. This study reports a case of non-infiltratingangiolipoma in a dog.Case: A 14-year-old mixed-breed dog was presented to a veterinary clinic in the city of Rio de Janeiro, RJ, Brazil. Onpalpation, a painless mass was noted, with high mobility and covered by intact hirsute skin in the right subcutaneousventrolateral region. Computed tomography of the chest showed an expansive mass of uptake only from the edges of thesoft tissues of the right subcutaneous ventrolateral region. The mass was homogeneous and well delimited, suggesting aneoplastic process. Subsequently, the mass was surgically removed, fixed in 10% buffered formalin, and sent for histopathological analysis. On macroscopic examination, the mass was well delimited, without skin coverage, and measured2.3×1.9×0.6 cm. The consistency was smooth and unctuous in appearance with a compact cream-colored surface withblackish multifocal spots. Under microscopy, the histological sections showed neoplasm of mature adipocytes and of endothelial cells of blood vessels benign were filled with a marked amount of red blood cells...

Background: In veterinary medicine, although primary lung tumors are rare compared to metastatic malignant neoplasms,an increase in the number of primary lung tumors in dogs has been reported in the past decades. Consequently, identifyingepidemiological, clinical, and pathological features of these neoplasms is essential for early and precise diagnosis. Thispaper aimed to report a case of a non-metastatic primary solid pulmonary adenocarcinoma in a dog and review the clinical,pathological, and immunohistochemical aspects of this neoplasm.Case: An 8-year-old female Cocker Spaniel was admitted to the Small Animals Veterinary Hospital of the Rural FederalUniversity of Rio de Janeiro (Brazil) with a history of progressive weight loss and clinical dyspnea. Physical examinationrevealed the following: body temperature, 38.7ºC; capillary refill time, one second; heart rate, 104 beats/min; respiratoryrate, 40 breaths/min; pallor mucosa; blood glucose, 133 mg/dL; and body score, 2 (1-9). A thoracic radiograph revealeda diffuse radiopaque pattern of the pulmonary parenchyma, pleural effusion, and a large mass that extended through bothhemithoraces. An ultrasound-guided cytological examination was performed and displayed moderate cellularity in a bloodybackground. Cells presented distinct cell borders, large bluish cytoplasm, round hyperchromatic or vesicular nuclei, andevident nucleoli. Three months after the first clinical consultation, the dog’s state kept deteriorating and the owner optedfor the euthanasia. Autopsy of the lungs showed multiple, poorly defined, coalescent nodules with an average size of20.0×15.0×10.0 cm. The nodules occupied roughly 70% of the pulmonary...

Background: Congenital cardiac diseases are a common cause of death in puppies. Tricuspid valve dysplasia is characterized by thickening and displacement of the leaflets of the tricuspid valve, agenesis of the valves, and incomplete separationof valve components. Papillary muscles may fuse and display shortened or absent chordae tendineae that contribute totricuspid regurgitation. Diagnostic features of tricuspid valve dysplasia include cardiomegaly with massive right atriumenlargement on thoracic radiography and tricuspid insufficiency on an ultrasound. We aimed to describe clinicopathological findings in a dog (Canis familiaris) with tricuspid dysplasia.Case: We aimed to describe tricuspid valve dysplasia in a dog referred for necropsy at the Anatomical Pathology Sector ofThe Rural Federal University of Rio de Janeiro, Brazil, with a clinical history of abdominal swelling, dyspnea, cyanosis,ascites, and prostration. Echocardiography and abdominal ultrasound revealed right ventricular enlargement, hepatomegaly,and splenomegaly. Examination of the heart showed prominent enlargement, thickening and dilation of the right chambers,thickening of the tricuspid leaflets, and moderately shortened chordae tendineae. The liver was enlarged, with a nutmegpattern, and foci of clotting and fibrin adhesions in the lateral right lobule.Discussion: Epidemiological, clinical, and pathological findings were consistent with tricuspid valve dysplasia. Althoughstructural abnormalities of the tricuspid and mitral valves are well known in fetuses and neonates, congenital and secondary tricuspid malformations are rare in dogs. The survival rate is associated with the severity of heart lesions. Tricuspidvalve dysplasia is mostly observed in large-breed...

Background: Emphysematous rumenitis is a condition characterized by gas filled bubbles or cysts in the ruminal mucosa. Although a similar pathology is reported from swine and humans, the incidence of this disease in cattle seems to be scarce. The etiology of emphysematous rumenitis is uncertain once many factors can be involved in its pathogeny, a single cause is difficult to ascertain. This lesion usually fails to display specific clinical signs; however, some degree of malabsorption and weight loss is expected. We described a case of emphysematous granulomatous submucosal rumenitis in a 2.5-yearold feedlot Nellore steer that presented reduction on daily weight gain.Case: Rumen fragments of a 2.5-year-old Nellore steer were submitted for histopathological evaluation at the Sector of Pathological Anatomy (SAP) of the Rural Federal University of Rio de Janeiro, Brazil. The specimens were part of an experimental trial to evaluate the effect of phosphorus (P) supplementation on nutrient intake, performance and P balance in fifty feedlot Nellore steers. Following a short adaptation period, in which behavioral observations were made twice daily to assess possible adverse factors, all steers were fed with balanced diet for one hundred and sixteen days. The steers were then slaughtered in order to evaluate macroscopic changes in the gastrointestinal system. Rumen and abomasum of each steer was emptied, washed with tap water and grossly examined. One steer presented ruminal lesion, while the other forty-nine did not show any ruminal injury. Throughout the experiment the affected steer showed reduction of daily weight gain; but during clinical examination no additional clinical sign was seen. At gross inspection, a reduction in the amount of muscular and adipose tissue was seen. Multiple coalescent bullous elevated structures measuring three to ten mm diameter were covering about 40% of the ruminal surface.[...]

Background: Leyomiosarcomas are uncommon malignant smooth muscle tumors of hollow organs. Bovine leyomiosarcomas have been described in several sites, but smooth muscle tumors that arise from the skin are rare in domestic animals. These neoplasms may show variable histologic features depending on their grade of differentiation; therefore, diagnostic tools as special stain, electron microscopy and immunohistochemistry are essential for the definitive diagnosis. Due to the lack of reports of skin leyomiosarcomas in cattle, we described the occurrence of a leyomiosarcoma in the skin and subcutaneous tissue of a Nellore cow. Case: A 10-year-old Zebu Nellore cow was admitted at the Veterinary Diagnosis Center (CEDIVET) of Pará Federal University (UFPA), Brazil, to investigate a tumor on the hip. At clinical examination the cow showed a decreased appetite and weight loss. Due to the bad prognosis the veterinarian recommended euthanasia. Representative tissue samples were submitted for histopathological and immunohistochemistry evaluation at the Department of Pathology of the Federal Rural University of Rio de Janeiro (UFRRJ). The slides were stained by Hematoxylin and Eosin (HE), Masson’s trichrome and Van Gieson stains and submitted for immunohistochemistry with primary antibodies vimentin, troponin C, smooth muscle alpha actin and desmin. Grossly, the tumor appeared as a multilobular, ulcerated and firm 30 cm diameter mass with black and hemorrhagic areas on the surface. The mass was scattered throughout the subcutaneous tissue and infiltrated the adjacent muscle. On light microscopy, the neoplasm consisted of a non-encapsulated proliferation into the derma, composed of highly pleomorphic spindle to round cells arranged in broad interlacing fascicles and small islands. Metastatic lesions were found in the lungs and local lymph nodes. Masson’s trichrome stain revealed collagen production and Van Gieson stains was inconsistent...
