Traumatic Panniculitis in a dog / Paniculite traumática em um cão

ABSTRACT

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
