panniculitis

[pənik′yəlī′tis]
Etymology: L, panniculus, piece of cloth; Gk, itis, inflammation
a chronic inflammation of subcutaneous fat in which the skin becomes hardened, particularly over the abdomen and thorax. Small subcutaneous masses of hard tissue are found in the affected areas. Some forms of the inflammation may be marked by the appearance of painless subcutaneous nodules on the lower extremities.

panniculitis

Inflammation and NECROSIS of the layer of fat under the skin especially in the abdomen. Nodular formation is common. Panniculitis is associated with trauma especially the trauma of repeated injections. It is also associated with a range of pancreatic disorders, including pancreatic cancer, and with multiple joint disorders (polyarthropathy). On microscopic examination, nodules of panniculitis show empty (‘ghost’) fat cells.

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
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.
sterile panniculitis

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