Clinical History: Two raccoons died in a pre-release rehabilitation pen in an interval of 1.5 weeks after appearing healthy. The second raccoon, a juvenile female, was submitted for postmortem examination. Necropsy Findings: In the small intestine, the subserosa is markedly hyperemic/congested (Fig. 1) with abundant watery, semi-translucid content and large amounts of tan-white mucus. The intestinal wall is thickened, and the mucosa is smooth and overlaid by thick mucus (Fig. 2). The large intestine contains moderate amounts of tan-yellow, mucoid digesta. Mesenteric lymph nodes are enlarged, the parenchyma is red and mildly protrudes on cut section.

We describe a case of hypertrophic gastropathy (Ménétrier’s like disease) with metastatic gastric adenocarcinoma in a seven-year-old intact female Labrador Retriever dog. The animal suddenly presented with emesis and died. Gross lesions included a marked diffuse thickening of the gastric mucosa and an ulcerated transmural neoplastic mass in the gastric body. Gastric body and fundus were affected by foveolar hyperplasia with loss of chief and parietal cells replaced by mucous cells and marked dilatation of gastric glands. An area of gastric adenocarcinoma with submucosal lymphatic vessels invasion was also present and metastases were observed in the gastric lymph nodes, small intestine, pancreas, lung and liver. Due to its similarity with other gastric proliferative disorders, including this condition in the list of differentials is a necessary step in the diagnostic investigation of canine gastropathies.

Pascalia glauca is a native weed and one of the most common hepatotoxic plant affecting cattle in Argentina. Although experimental P. glauca poisoning have been reported in sheep, no spontaneous cases have been reported in this species. This work describes an outbreak of intoxication after spontaneous consumption of P. glauca, affecting 20% (6/30) sheep of a commercial flock. Affected sheep were ataxic, depressive, with mucous nasal discharge, cough and abdominal breathing. During post mortem examination, liver was swollen and a diffuse enhancement of the reticular pattern (“nutmeg liver”) was visible. Histopathological examination reveals severe and extensive acute diffuse centrilobular hepatic necrosis with hemorrhage. The presence of the toxic plant, the clinical and pathological findings allows us to confirm the etiology of this outbreak.

A nine-year-old, male, Pekingese dog was presented with a history of dyspnea, lethargy, syncope, polyuria, polydipsia, and selective appetite over two years. When the clinical signs first began, a radiographic exam revealed a radiopaque mass in the cranial mediastinum. An adequate treatment was not performed and the dog was presented to the hospital with severe tachycardia, dyspnea, and tachypnea, and died during physical examination. On necropsy, the heart presented bilateral auricular aneurysms. The pericardial sac was intact, and no other defects were found within the heart. Microscopically, the cardiomyocytes were marked degenerated and proliferation of connective tissue. This is the first case report of a bilateral auricular aneurysm with intact pericardial sac in a dog.

Forensic veterinary pathology is essential to identify the cause of death of animals with suspicion of abuse, neglect, exogenous intoxication, medical errors, if the lesions were accidental or ante-mortem or in cases where the animal’s identity is needed. It involves several areas that can be used to determine the cause of death in animals, such as traumatology, entomology and toxicology. This work aims to determine the main lesions found in judicial necropsies of animals from the metropolitan region of Belém, qualifying the most prevalent lesions according to the classification in forensic traumatology. The necropsy was performed according to the animal species and using the method of Ghon. The animals were grouping by specie, sex, race and age and it was made a segmentation by vulnerable energy. 33 judicial necropsies (9.06%) were performed between January 2018 and December 2019, including 22 canines (66.7%), seven felines (21.2%), two farm animals (6.1%) and two wild animals (6.1%). Regarding the sex of the animals, in general, 51.51% were males and 45.45% were females. Young dogs and cats represented the highest percentage of cases. Mixed breed dogs were the most prevalent, with 31.8%. In all species, the most prevalent energy was chemical energy, totalling 18 cases. Second, with six cases, mechanical trauma with only canines and felines, in which, only in three were evident the blunt injury. In only one case, the suspicion was of biodynamic energy, with suggestive findings. In conclusion, the forensic necropsy associated with the animal’s history is capable of providing relevant information which assists the pathologist in the search for injuries, its identification and interpretation.

Mammary gland tumors are one of the most commonly diagnosed tumors in female dogs, with a reported prevalence ranging from 26 to 73% in Brazil. In recognition of the importance of these tumors veterinary researchers and clinicians in Brazil produced the first consensus statement regarding canine mammary tumors in 2010. The intention was to establish criteria for diagnosis, prognosis, and treatment. This study evaluated the methods of prevention, diagnosis, treatment, and determination of prognosis used by veterinarians in Brazil, and sought to quantify the number of veterinarians who were aware of the consensus statement. One hundred and three veterinary clinics participated in the study, 87.37% of which recommend early neutering as a preventative treatment for mammary tumors. For diagnosis, 100% of these use laboratory testing, 94.17% perform chest radiography, 78.64% incisional biopsies, 44.66% cytological analysis, and 13.59% immunohistochemical analysis. The most common surgical procedure is unilateral mastectomy (72.81%), and chemotherapy is performed in 49.51% of the clinics. Of the 103 clinics, 66.01% were aware of the consensus. Although knowledge of the consensus statement is widespread among veterinarians in Brazil, not all its recommendations are being followed. Preventive actions for canine mammary tumors are well established in most parts of the country. However, the consensus statement has had little influence on informing prognostic and therapeutic approaches, with a poor uptake of surgical removal of lymph nodes and immunohistochemical examination.

Cecal dilatation and distention is an important disorder in early lactation dairy cows, however, reports describing the anatomical pathology findings of this condition are scarce in the literature. Etiopathogenesis of cecal dilatation and distention is often attributed to high concentrate feeds, but there is also evidence of myoelectrical dysfunction contributing to its occurrence. Diagnosis is often made based on physical exam findings, with the contribution of ancillary exams. This paper aims to describe a case of cecal dilatation with clinical, laboratorial and pathology findings of a 5-month-old Holstein calf that presented abdominal distension, positive succussion of the right flank and mild dehydration. Clinical pathology findings included neutrophilic leukocytosis with regenerative left shift and elevated ruminal chloride. Ultrasonographic examination of the right abdomen showed distended and hypomotile intestinal loops. Despite that, due to the patient’s age, which prevented rectal palpation, and lack of some characteristic clinical and clinical pathology findings, diagnosis was only possible post mortem. Macroscopical and microscopical findings demonstrated cecum dilatation with edema, hemorrhage and thrombi. Despite being well known by large animal clinics, anatomical pathologists must be aware of this condition.

Necropsy findings included moderate accumulation of light red fluid in the abdominal and thoracic cavities, mild hemoglobin imbibition, as well as collapsed lungs (Fig. 1). The liver was markedly enlarged, had rounded edges, and moderate, diffuse yellow discoloration. The gallbladder was filled with thick, grumous bile, and the spleen was moderately enlarged. The kidneys had moderate diffuse dark red discoloration, and the urinary bladder was distended with dark-red urine (Fig. 2). The grey matter of the brain and the spinal cord was markedly pink-red discolored (Fig. 3). Squashes of the spleen and brain were prepared and routinely stained with PanóticoRápido® (Laborclin, Brazil) (Fig. 4).

Congenital malformations are morphofunctional abnormalities of tissues and organs that can occur during embryonic or fetal development in all animal species. Among these, dicephalus is characterized by the development of an individual with two heads and two necks, due to the total duplication of facial, cranial, and brain structures. Reports of dicephalus in cattle are scarce and do not normally emphasize radiographic and bone anatomy characteristics. The objective was to describe a case of a stillborn dicephalus calf. The duplication of the head, brain, neck, and two thoracic vertebral columns, isolated from each other, with 13 vertebrae each was verified radiographically. There were 13 pairs of ribs, the ones on the right side articulated with the thoracic spine on the right and the left ones with the spine on the left. Caudally at T13, there was only one lumbar spine, sacral and coccygeal. In the ventrodorsal projection, L1, L2, L3, and L6 had the shape of a butterfly (suggestive of hemivertebrae). At necropsy, in addition to craniocervical and spinal morphological changes, collapsed lungs, duplication of the heart with anastomosis between the aortic arches of the hearts, and duplication of the upper digestive tract were observed. Additionally, there was arthrogryposis of the pelvic limbs. Corpse maceration, followed by the skeletal assembly, showed the bone changes previously observed and confirmed the suspicion of hemivertebrae.

Pythiosis is a granulomatous process of which the oomycete Pythium insidiosum is its etiological agent. It can affect animals and humans alike and its infection occurs when free zoospores in the water get in contact with the target tissues and encyst. The disease often occurs in tropical places with abundance of water and aquatic plants that host the fungus. Dogs infection is predominantly gastric with granuloma formations in the stomach and intestine with progressive signs of vomiting, weight loss and diarrhea. In this case report, we described clinical, surgical, necroscopic and histopathological findings of a one year and two months old, male boxer that presented clinical signs of anorexia and persistent vomiting. It was noticed on ultrasound examination an increase in stomach and intestine thickness. Laparotomy confirmed a mass affecting the gastric wall which, an incision biopsy, showed an abundant fibrous tissue associated with granulomatous reaction that was surrounded by tubuliform structures. Due to clinical complications, euthanasia was performed and in necroscopic examination a markedly increased stomach and duodenum was observed. An; histological examination of this areas it was observed that they contained granulation tissue with giant cells and epithelioids macrophages around necrosed areas associated with lymphocytes infiltrate. Also, it was possible to observe tubuliform structures by the Grocott-Gomori’s Methenamine Silver (GMS) stain, this finding is compatible with the agent Pythium insidiosum. Therefore, this presumptive identification was confirmed by PCR analysis which amplicon had 97.83% similarity with current available genomic sequence of P. insidiosum.
