Lipedema is a chronic vascular disease almost exclusively of female se
x, characterized by the deposit of fat on the legs, with an ''Egyptian
column'' shape, orthostatic edema, hypothermia of the skin, alteratio
n of the plantar support, and negativity of Stemmer's sign. The etiolo
gy and pathogenesis of this disease are still the object of study, and
therapy is very difficult. Various authors have described morphologic
and functional alterations of prelymphatic structures and of lymphati
c vessels. The big veins remain untouched in the phlebograms and an al
teration of the skin elasticity is demonstrated. The present authors h
ave studied by dynamic lymphoscintigraphy 12 women patients suffering
from lipedema, and compared the results with those of 5 normal subject
s and 5 patients suffering from idiopathic lymphedema who were sex and
age matched with the patients suffering from lipedema. The patients s
uffering from lipedema showed an abnormal lymphoscintigraphic pattern
with a slowing of the lymphatic flow that presented some analogies to
the alterations found in the patients suffering from lymphedema. A fre
quent asymmetry was also noticed in the lymphoscintigraphic findings t
hat is in contrast to the symmetry of the clinical profile.
