    "definition": "A rare genetic primary lymphedema characterized by unilateral or bilateral lower limb lymphedema of variable severity. The condition shows almost complete penetrance with onset in childhood or adolescence in females, whereas in males it shows incomplete penetrance with later onset of disease. Lymphoscintigraphy in more severely affected individuals reveals lymphatic abnormalities consistent with lymphangiectasia, valve dysfunction, and thoracic duct reflux."

        "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."
