Sterile nodular panniculitis in a Maltese dog[1]

Sterile nodular panniculitis is an immune-mediated disease of dogs which manifests both locally and systemically[2].

The disease is characterized by fever and multiple subcutaneous nodules[3], but in more rare cases systemic signs have been observed such as sterile neutrophilic-macrophagic lymphadenitis with vasculitis associated with gastrointestinal and pulmonary signs[4].

Pansteatitis is commonly associated with this disease, presenting as inflammation of subcutaneous, mesenteric and falciform fat[5].

Microbiological examination of tissues is usually negative.

Diagnosis is based on histological analysis of biopsied tissue samples. A definitive diagnosis requires multiple skin biopsies.

Other ancillary tests may be indicated, such as measurement of serum alpha1 antitrypsin, which can help establish an association with serum alpha-1 antitrypsin deficiency[6].

Treatment involves use of immunosuppressive drugs such as prednisolone or cyclosporine.
