A hereditary condition where the lymph vessels are blocked and the legs swell [Described 1892. After William Forsyth Milroy (1855-1942), Professor of Clinical Medicine in Nebraska, USA.]
A hereditary variation of lymphedema (the buildup of lymphatic fluid in tissues) arising due to an abnormal development of lymphatic vessels, hindering the unobstructed movement of lymph. This condition is inherited through an autosomal dominant genetic pattern and is present since birth. Typically, it predominantly impacts the legs.
