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.","PeriodicalId":9223,"journal":{"name":"Brazilian Journal of Veterinary Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43458646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":9223,"journal":{"name":"Brazilian Journal of Veterinary Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41319881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":9223,"journal":{"name":"Brazilian Journal of Veterinary Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47757295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
