Several case reports including Linder

Pancreatic panniculitis.

Panniculitis linked to pancreatic disease occurs rarely in dogs. Pancreatitis is the main cause, but pancreatic neoplasia is also reported to induce this. It could be because of concurrent pancreatitis.

Lesions appear to be on the limbs and can be symmetrical. Periarticular regions and the medulla of bones can be affected.

Potassium bromide associated panniculitis

Boynosky and Stokking (2014) reported on 2 dogs treated for idiopathic epilepsy with potassium bromide for over one year. Both dogs developed painful subcutaneous nodules over the trunk. These fistulated, waxed and wained or persisted. When pottassium bromide was discontinued, the nodules ceased to form and relolved

Sterile Nodular Panniculitis (SNP)

Sterile nodular panniculitis is a disease centered on the lobules of fat in the panniculus. The lesions are multiple subcutaneous nodules that may wax and wain, and may fistulate. They have a pyogranulomatous to granulomatous panniculitis for which no infectious agent can be identified. Response to corticosteroids is a final clinical confirmation of this disease as infectous disease should not respond to this extent in the long term.

Dogs may have concurrent disease such as systemic lupus erythematosis, rheumatoid arthritis, polyarthritis, lymphoplasmacytic colitis, and hepatic disease (O'Kell et al 2010), atopic dermatitis and primary hypoadrenocorticism (Kim et al 2011), or polyarthritis only(Contreary et al 2015)

Australian shepherd dogs, Brittany spaniels, Dalmatians, Pomeranians and Chihuahuas were significantly over-represented (Contreary et al 2015)
