NCIt definition : A congenital condition that results in swelling in the arms or legs, and can occur
during adolescence or adulthood. Loss of motion and pain may also accompany the swelling.
Protein-rich lymphatic fluid accumulates in tissues, engorging and enlarging vessels
and often causing visible swelling, tenderness, and pain. Left untreated, the affected
tissues may continue to swell, and can become hardened or fibrotic and susceptible
to infection.;
