Sterile nodular panniculitis and pansteatitis in three weimaraners.

The clinical and pathological findings in three unrelated weimaraners with pyrexia and multiple subcutaneous nodules are reported. Abdominal pain was an additional feature in two of the dogs and clinical investigations revealed inflammation of subcutaneous, mesenteric and falciform fat. Histopathological findings were consistent with pansteatitis. In the third dog, lesions were apparently limited to the subcutis and, hence, a diagnosis of nodular panniculitis was made. Microbiological examination of tissues was negative in all dogs, and there was no evidence of pancreatic disease. This report thus describes a presumed sterile and idiopathic panniculitis/pansteatitis complex in weimaraner dogs. Although the aetiology is unknown, this may represent an immune-mediated disorder.
