There are no reports of what kind of spleen tumors have developed within a certain period of time in Uruguay. Therefore, we investigated spleen tumors that were surgically resected and brought into our laboratory for a year (2019-2020). As a result, 9 splenic tumors were observed. Hemangiosarcomas occurred at the highest incidence in 6 of 9 cases. In addition, 1 case each of lymphoma, fibrosarcoma, and perivascular wall tumor was observed. Furthermore, the perivascular wall tumor, which has not been reported so far, was observed in a seven years-old female Cocker Spaniel.

We studied a 14-year-old male dog necropsied. Gross findings were hemorrhagic nodules in the spleen, liver, heart and abdominal and thoracic lymph nodes. Histologically, we homogeneously observed tumor cells often with prominent, bulging and mitotic nuclei that were pleomorphic and hyperchromatic, forming small blood vessels. Tumors in all organs were diagnosed as capillary hemangiosarcomas. No tumor cells were detected in the lungs. We presume that the primary tumor was present in the spleen, from where it metastasized multiple organs via lymphatic vessels.

A 1-year-old female Yorkshire terrier was presented to the clinic for a second opinion regarding its poor hair coat condition. According to the owner, the dog has been showing that appearance since the moment it was adopted, at 8 months of age. The owner also mentioned that the dog’s father had a similar fur appearance. External deworming was regularly administered to this dog, and oral fluralaner (Bravecto™) was given at the time of its presentation. No other clinical signs were reported. A complete physical examination was performed, with emphasis on skin and fur assessment. The main findings were the presence of extensive areas of hypotrichosis and alopecia, affecting only dark-haired regions, mainly in the dorsal region, neck and on the outer surface of both pinnae (Figures 1 and 2). The presence of seborrhea and small papules compatible with superficial folliculitis were also identified. No other abnormalities were detected during the remaining examination. The complete blood count and serum biochemistry, including total circulating thyroxine (tT4) were unremarkable. Deep skin scraping and dermatophyte culture were also performed, but both tests were negative for the presence of ectoparasites and fungi, respectively. Finally, the hair follicles from the lesion areas were pulled out and evaluated under a microscope using the trichogram technique. Baths with an anti-seborrheic and anti-microbial shampoo were prescribed, but although seborrhea and folliculitis were quickly controlled with this topical treatment, the alopecic areas remained and no signs of hair regrowth was observed in the following dermatological reassessments.

A senile female nocturnal curassow (Nothocrax urumutum) kept under human care was found dead. Grossly, the lungs were congested and had a nodule with 2.0 cm in diameter adhered to the left lung. Histologically, there were multifocal to coalescent areas of necrosis characterized by deposition of amorphous and eosinophilic material with large amount of cellular debris, surrounded by numerous epithelioid macrophages, multinucleated Langhans giant cells, occasional lymphocytes and plasma cells. Ziehl-Neelsen stained sections demonstrated myriad of intralesional alcohol-acid resistant bacilli (BAAR). DNA extracted from lung samples were evaluated by nested polymerase chain reaction resulting in mycobacterial DNA identification. This is the first reported case of mycobacteriosis in a nocturnal curassow.

Primary tracheal neoplasms are uncommon and poorly documented in veterinary medicine, being most frequently reported in domestic cats. Squamous cell carcinoma (SCC) is a malignant neoplasm that originates from the stratified squamous epithelium, considered one of the most common skin neoplasms in dogs and cats. This paper aims to report the anatomopathological and immunohistochemical findings of a clinical case of primary SCC in the trachea of a female Schnauzer canine, attended at the Veterinary Hospital Luiz Quintiliano de Oliveira of the Faculty of Veterinary Medicine of Araçatuba (FMVA – UNESP), complaining of choking, coughing and dyspnea for 1 month. The tracheal portion affected by the neoplasm was sent to the Veterinary Pathology department of the FMVA after surgical excision. Fragments of the neoplasm were collected and fixed in 10% formaldehyde for further histopathological and immunohistochemical analysis. Microscopically, the neoplasm was well differentiated, being characterized by the presence of keratin pearls, low degree of pleomorphism and rare mitotic figures. In the immunohistochemical analysis, there was immunoexpression of anti-cytokeratin antibodies AE1AE3, 34BE12, CK14 and CK5/6, confirming the diagnosis of squamous cell carcinoma. In about 30% of the cells there was immunostaining for Ki67 antibodies, justifying the low mitotic index of tumor cells and the few images of mitosis seen. Due to the rare occurrence of primary tracheal SCC in dogs, the use of diversified diagnostic techniques is important in order to better understand the biological behavior of this neoplasm in unusual anatomical locations.
原发性气管肿瘤在兽医学中并不常见，文献记载也很少，最常报道的是家猫。鳞状细胞癌(SCC)是一种起源于分层鳞状上皮的恶性肿瘤，被认为是狗和猫最常见的皮肤肿瘤之一。本文报告一只雌性雪纳瑞犬气管原发性SCC的解剖病理和免疫组织化学结果，该病例在araparatuba兽医学院Luiz Quintiliano de Oliveira兽医医院(FMVA - UNESP)就诊，主叫窒息、咳嗽和呼吸困难1个月。受肿瘤影响的气管部分在手术切除后被送往FMVA兽医病理学部。收集肿瘤碎片并在10%甲醛中固定，用于进一步的组织病理学和免疫组织化学分析。显微镜下，肿瘤分化良好，角蛋白珠状，多形性程度低，罕见有丝分裂象。免疫组化分析发现抗细胞角蛋白抗体AE1AE3、34BE12、CK14、CK5/6免疫表达，证实为鳞状细胞癌。在大约30%的细胞中有Ki67抗体的免疫染色，证明肿瘤细胞的有丝分裂指数低，有丝分裂图像很少。由于犬原发性气管鳞状细胞癌的罕见发生，为了更好地了解这种肿瘤在不同解剖位置的生物学行为，使用多样化的诊断技术是很重要的。

Intracranial lipomas, also called intracranial lipomatous hamartomas, have been reported in some strains of research mice, but are rare in C57BL6 strains. It is presumed based on current publications that this is the first report of an intracranial lipoma in a mouse with this genetic change (B6.Cg-Cnpy2 tm1.2 Zhli Alb-Cre). Grossly, a fur-covered, soft, cylindrical, exophytic mass on the dorsal midline of the cranium was evident. Upon dissection, a soft, white, tubular structure extended through a 1mm defect in the sagittal suture of the skull to the deep surface of the hypodermis. Histologically, the mass consisted of well demarcated proliferation of mature white adipocytes, each containing one large fat droplet. The mass extended from the cerebrum at the level just caudal to the hippocampus in the third ventricle, between the superior colliculus and the caudal portion of the retrosplenial area and through the sagittal suture to the hypodermis and was surrounded by normal brain tissue.

The reported prevalence of canine hepatoid gland tumor (HGT) varies widelyowing mainly to the lack of well-defined diagnostic criteria and poor interobserver agreement. The aim of the present study was to improve the level of diagnostic agreement among pathologists in canine HGT. Five pathologists diagnosed and classified morphological features in 57 cases of canine HGT and, based on their reports, diagnostic algorithms were devised using recursive partitioning analysis. The proportion of diagnoses of malignant hepatoid neoplasia among the five pathologists ranged from 26.3 to 50.9%. Interobserver diagnostic agreement was classified as fair (κ=0.54) but improved to good (κ~0.65) following application of two novel diagnostic algorithms based on histomorphological features as sebaceous differentiation, mitotic count, atypical mitosis and cellular atypia. This study has demonstrated that interobserver agreement in the diagnosis of canine HGT could be improved using novel algorithms. Further analyses are warranted to validate the proposed classification systems applying a higher sampling of canine HGTs.

Clinical History: A one-year-old female Texel sheep had anorexia and jaundice. After one day, the clinical condition progressed to lethargy, lateral recumbency, and death within hours. The sheep was part of a flock of 20 housed indoors and received an increasing amount of feed (specific for sheep) for the last two months. Gross Findings: The sheep was in excellent body condition. The carcass was discolored by marked icterus. In the subcutaneous tissue, there was multifocal petechiae and ecchymosis. The kidneys had a deep red-brown discoloration. The urinary bladder was distended and filled with dark red to black urine. The liver was slightly soft and swollen, with a deep orange hue. The gallbladder was distended and filled with dark grumous bile.

A 2-month-old male domestic shorthair cat was referred to a private veterinary clinic with a history of dyspnea and inappetence. At the clinical examination, the cat was in poor body condition, with hyperthermia and abdominal distension. No major abnormalities were observed in the thoracic radiographs or abdominal ultrasound. A complete blood count revealed leukocytosis with neutrophilia. Although no clinical diagnosis was made, the cat received support therapy, but went into cardiac arrest and died. The cat was submitted for necropsy and the main gross finding was two white nodules on the ventral surface of the thoracic vertebrae (from T1 to T4). At the cut surface, the nodules were friable and filled with yellow exudate. The epidural space of the thoracic region was filled with yellowish viscous material. Histologically, the vertebrae were partially replaced by abscess formation characterized by a necrotic center with degenerate neutrophils, surrounded by fibrous connective tissue. The epidural space was filled with degenerate neutrophils, necrotic debris, fibrin, and intralesional colonies of gram-negative short rod-shaped to coccobacillary bacteria. Bacteriologic culture yielded Pasteurella multocida. This paper describes the gross, histological, and bacteriological features of a rare case of spinal epidural empyema caused by Pasteurella multocida in a cat.

Cryptorchidism is the incomplete descent of the testes and associated structures, and cryptorchid testes are more likely to develop testicular neoplasms, such as seminoma. This is the first report of a seminoma in a cryptorchid wild-caught gray brocket deer (Mazama gouazoubira). The animal developed a unilateral seminoma with classical histopathological findings and benign behavior. Six months after the orchiectomy the cervid presented a metatarsal opened fracture, dying during the orthopedic surgery. No macro or micrometric metastasis was observed at the necropsy.
