AbstractLymphedema is a localized form of tissue swelling, characterized by a progressive
accumulation of a tissue fluid in the interstitial compartment as a result of
the lymphatic system dysfunction. It is a rare disease in the pediatric
population and in the majority of cases it is a consequence of an abnormal
formation of the lymphatic system, which is called primary lymphedema. Although
its epidemiology is not precise, it is assumed that 1:100 000 children suffer
from primary lymphedema. The diagnosis can be made by a proper clinical
examination after ruling out secondary causes of lymphedema, particularly in
cases with a more asymmetric swelling of the extremities. In this very article
we present a case report of an 8-months-old infant with primary lymphedema, who
had presented swelling of the extremities from birth and yet no pathology was
suspected before. The purpose of this article is to draw attention to the fact
that a baby with excessive subcutaneous tissue is not always a healthy, chubby
infant with considerable amount of fat tissue.
