Panniculitis is a group of diseases whose hallmark is inflammation of the subcutaneous adipose tissue that may be challenging both for the clinician and the dermatopathologist. It can occur in any fatty tissue (cutaneous or visceral) and is often diagnosed on the basis of a deep skin biopsy. Though mesenteric panniculitis is a common entity, and often associated with intra-abdominal inflammator...

Lupus erythematosus panniculitis (profundus), a rare variant of chronic panniculitis, sometimes develops during the course of discoid lupus erythematosus or systemic lupus erythematosus. A 61-year-old woman had suffered from autoimmune hepatitis type I for 5 years. Prednisolone had been administered as maintenance therapy and her hepatitis had been well controlled. However, asymptomatic erythem...

UNLABELLED INTRODUCTION Eosinophilic panniculitis is an unusual type of panniculitis characterized by a prominent infiltration of subcutaneous fat with eosinophils without an exact etiopathogenesis. To the best of our knowledge, up to now eosinophilic panniculitis has been described in only one previous case with human immunodeficiency virus disease in the literature. CASE PRESENTATION Her...

Panniculitis is a rarely reported clinical finding in dermatomyositis. It may precede the other manifestations associated with dermatomyositis by as much as 14 months. In all cases, myositis and panniculitis improve simultaneously during treatment. The present report describes the case of a 30-year-old female patient with clinical and histopathological findings consistent with panniculitis two ...

Lupus panniculitis is a rare manifestation of cutaneous lupus erythematosus, which may lead to major aesthetic sequelae with a severe impact on patients' quality of life. We report 2 cases supporting the short- and long-term efficacy and safety of lipofilling in the treatment of lupus panniculitis-induced atrophy. These observations pave the way for prospective, larger-scale studies in patients...

A case of systemic nodular panniculitis is described in which the myocardium was found at necropsy to be extensively involved with focal interstitial carditis, identical histologically with nodules of panniculitis biopsied from the skin. This degree of myocardial involvement, which was not apparent during life and was not confined to pericardial or myocardial adipose tissue, has not previously ...

To the Editor: Popsicle panniculitis is a type of cold panniculitis that affects the cheeks of young children, is self-limited, and may be mistaken for cellulitis. The diagnosis may be missed unless a detailed history is elicited. We present a 5-month-old child who developed bilateral popsicle panniculitis on his cheeks despite being on systemic prednisolone for a large facial hemangioma. A 5-m...

Alpha-1-Antitrypsin (AAT) deficiency associated panniculitis is commonly included in the dermatologist's differential diagnosis but the disease is rarely ever diagnosed or discussed. The pathophysiology, clinical presentation, histopathology, diagnosis, and treatment of AAT deficiency panniculitis will be reviewed.

A rare triad composed of lobular panniculitis in the setting of pancreatitis and polyarthritis is termed panniculitis, pancreatitis, and polyarthritis (PPP) syndrome. Pancreatic panniculitis is a rare form of subcutaneous fat necrosis associated with underlying pancreatic disease. We describe a case of PPP syndrome and review the relevant literature associated with this rare clinical syndrome. ...

Mesenteric panniculitis is a rare condition of unknown etiology that causes inflammation of the adipose tissue in the mesentery. We describe a case in which mesenteric panniculitis was diagnosed on the basis of imaging and resolved spontaneously.
