RESUMO
A displasia renal é caracterizada como uma desordem do parênquima renal. Ocorre no período embrionário durante a diferenciação dos tecidos renais e sua etiologia ainda permanece indefinida. Esta patologia, de origem congênita e hereditária, acomete principalmente animais jovens. A afecção pode levar ao desenvolvimento de doença renal crônica, com manifestação clínica de poliúria, polidipsia, perda de peso e apatia. Exames de imagem auxiliam na avaliação da arquitetura renal, evidenciando áreas de perda da definição córtico-medular. O diagnóstico definitivo é obtido por histopatologia. Destaca-se a importância de evitar o cruzamento de animais portadores de displasia renal, pois a doença é de caráter transmissível. O presente trabalho tem por objetivo relatar um caso de displasia renal, em um canino da raça Lhasa-apso, caracterizando seus aspectos clínicos, ultrassonográficos e anatomopatológicos.
Renal dysplasia is characterized as a disorder of the renal parenchyma. It occurs in the embryonic period during differentiation of renal tissues and its etiology remains unclear. This congenital and hereditary pathology affects mainly young animals. The condition can lead to the development of chronic kidney disease with clinical signs of polyuria, polydipsia, weight loss and apathy. Imaging tests help the evaluation of renal architecture, highlighting areas of loss of cortical-medular definition. The definitive diagnosis is made by histopathology. Highlights the importance of avoiding crossing animals with renal dysplasia, because the disease is transmitted character. This paper aims to report a case of renal dysplasia in a Lhasa-apso canine, featuring its clinical, ultrasonographic and anatomopathological aspects.

Background: Panniculitis can be associated with a group of multifactorial diseases that develop intense inflammatory response of the subcutaneous fat tissue. The damaged fat cells suffer hydrolysis and saponification. The etiology remains unknown, although it has been associated with infectious agents, vascular pathologies, pancreatic disorders, neoplasms, immunologic diseases and nutritional deficiencies. Nodular sterile panniculitis is referred to the fat subcutaneous tissue inflammation without the presence of microorganisms and generally is presented with multiple or single nodules associated either with systemic or traumatic issues. This assay reports a case of traumatic Panniculitis presented as a single nodule on a dog admitted at the Veterinary Teaching Hospital of Passo Fundo University (HV-UPF), State of Rio Grande do Sul, Brazil, emphasizing the clinical signs, diagnosis and surgical treatment. Case: An adult mixed breed bitch, weighting 7,5 kg, was admitted at the HV-UPF because of a one-month evolution of a dorsal thoracic subcutaneous mass. Symptomatic treatment with unknown oral antibiotics was administered by another veterinarian, who also tried to perform local puncture drainage unsuccessfully. There was no previous history of local puncture or subcutaneous drug infiltration that could explain the mass. During physical examination, a single, painless and nodular subcutaneous mass (4 x 6 cm) was located on the dorsal thoracic median line, below the scapula, discharging a serosanguineous fluid probably due to the previous puncture. No other occurrences were found. The patient was treated with cephalexin and meloxicam. Hematological and biochemistry examinations were within reference range. Cytological exam demonstrated slightly degenerated neutrophilis and a great amount of adipose tissue. This could suggest, among other pathologies, neoplasm. Surgery was performed after 15 days. An elliptical incision was performed maintaining a 2,5 cm safety margin from the mass. Histopathological findings were compatible with sterile nodular panniculitis, likely traumatic. Discussion: There was a single, firm, regular, painless nodule, correspondent with other studies. The lesion location was also similar to other author's findings. Cytological findings were unspecific and could lead to several diagnoses. Careful pathologic study is necessary to differentiate from benign or malignant neoplasms and other affections. The hematological and biochemistry examinations, ultrasounds and radiographs were all within reference range on the case. These diagnose tools are very important and should always be used in order to achieve the correct screening, diagnosis and treatment. Surgical removal was considered effective, once 7 months after the treatment there was no local recurrence, with great cosmetic result.
