Definition: Benign DERMATOSIS caused by a loss of dermal ELASTIC TISSUE resulting in localized sac-like areas of flaccid skin. It can be either primary (idiopathic) or secondary to other skin conditions, PENICILLAMINE use, or premature birth.
do not confuse with CUTIS LAXA, mostly a genetic disease: both are described as "loose skin"
