title: The pathogenesis of congenital hereditary lymphedema in the pig.
abstract: The morphogenesis of congenital hereditary lymphedema was studied in pigs. The disorder, which is essentially a general underdevelopment or even total non-development of the lymphatic system proved to be present during the whole period of lymphatic development. It is suggested that a retardation in the differentiation of the lymphatic primordia from the primitive veins is the early event regulated by a chromosomal aberration. The longer this delay the more serious the lymphatic malformations.
