The flow or discharge of chyle. In patients affected by complex lymphangiodysplasias with involvement of chyliferous vessels, with clinical presence of chylous reflux and subsequent lymph-chyledema of external genitalia and lower extremities, chylorrhea may often occur out of lymphostatic warts in the scrotum, in the inguinal-perineal region, or in the lower extremities. It differs from standard lymphorrhoea, because the discharge consists of a milky – not simply serous – fluid. This is an important difference in clinical differential diagnosis, to distinguish a lymphedema proper from a lympho-chyledema, without needing any particular diagnostic procedure, like lymphography.
