panniculitis

a rare multifactorial inflammatory condition involving subcutaneous fat.

lobular panniculitis

the inflammatory process primarily involves the fat lobules rather than the interlobular connective tissue.

lupus panniculitis

see lupus erythematosus.

necrotizing panniculitis

multifocal, non-pruritic cutaneous nodules which may ulcerate and discharge serous fluid; recorded in dogs. See also nodular panniculitis (below).

nodular panniculitis

subcutaneous nodules that may become cystic or ulcerate or develop fistulous tracts that drain an oily material. They occur in dogs, cats and horses, and may be sterile or caused by infectious agents.

nodular nonsuppurative panniculitis

a disease marked by fever and the formation of tender, sterile nodules in the subcutaneous fatty tissues which drain oily, bloody material. Occurs in dogs, particularly Dachshunds. Similar to Weber-Christian or Christian-Weber disease in humans. Called also sterile panniculitis, or relapsing, febrile, nonsuppurative panniculitis.

postinjection panniculitis

occurs after a subcutaneous injection; a discrete nodule with a necrotic center.

pyogranulomatous panniculitis

see opportunist mycobacterial granuloma.

relapsing, febrile, nonsuppurative panniculitis

seenodular nonsuppurative panniculitis (above).

septal panniculitis

the inflammatory process primarily involves the interlobular connective tissue septae rather than the fat lobules.

Weber-Christian panniculitis

a subcutaneous panniculitis with systemic features. See nodular nonsuppurative panniculitis (above).
