Lipoatrophy is the term describing the localized loss of fat tissue. This may occur as a result of subcutaneous injections of insulin in the treatment of diabetes , from the use of human growth hormone or from subcutaneous injections of copaxone used for the treatment of multiple sclerosis .
Lipoatrophy is most commonly seen in patients treated with thymidine analogues and other older HIV drug treatments such as the nucleoside reverse transcriptase inhibitors [NRTIs] [9] like zidovudine (AZT) and stavudine (d4T). [10] Other lipodystrophies manifest as lipid redistribution, with excess, or lack of, fat in various regions of the body ...
Acquired generalized lipodystrophy (AGL), also known as Lawrence syndrome [1] and Lawrence–Seip syndrome, [1] is a rare skin condition that appears during childhood or adolescence, characterized by fat loss affecting large areas of the body, particularly the face, arms, and legs.
Lipoatrophia semicircularis, also known as semicircular lipoatrophy, [1] is a medical condition in humans, commonly known as ribbed thighs. It consists of a semicircular zone of atrophy of the subcutaneous fatty tissue located mostly on the front of the thighs .
Idiopathic localized involutional lipoatrophy (ILIL) is a rare and nosologically imprecise condition characterized by a focal loss of subcutaneous tissue on one or several sites, occurring without any significant triggering factor or auto-immune background, and regressing spontaneously within a few months.
Congenital generalized lipodystrophy (also known as Berardinelli–Seip lipodystrophy) is an extremely rare autosomal recessive condition, characterized by an extreme scarcity of fat in the subcutaneous tissues. [2]
Primary anetoderma is an idiopathic development of atrophic lesions in skin areas that appeared normal prior to the onset of atrophy. [7]Secondary anetoderma is a skin disease that develops in areas where there has previously been or is currently skin pathology.
In a sense, the "opposite" of injection site lipohypertrophy is injection site lipoatrophy, in which the subcutaneous fat around an injected area "melts away" over a few weeks or months, leaving unsightly, well-demarcated depressions in the skin. The mechanism of this local lipoatrophy is not understood and may involve autoimmunity or local ...
