Definition and Characteristics

The lipodystrophy syndromes are rare disorders characterized by the loss of adipose tissue [1]. The loss of fat tissue can have genetic, immune, or infectious/drug-associated causes. Metabolic complications, such as insulin resistance, diabetes mellitus, hypertriglyceridemia, and fatty liver, increase in severity with the extent of fat loss. Lipodystrophies can be divided into two subtypes: familial and acquired. Causative mutations have recently been identified in one form of familial lipodystrophy as well as in one form of acquired lipodystrophy. Several mouse models might help understanding the development of these syndromes.

Panniculitis describes a clinical symptom caused by an inflammation of subcutaneous adipose tissue followed by a loss of adipose tissue. Panniculitis may be a sign of some forms of acquired lipodystrophy. Panniculitis may occur as an autoimmune...
