CONGENITAL HEREDITY LYMPHEDEMA IN THE PIG

Abstract

A histopathological investigation was performed in
newborn pigs with congenital hereditary lymphedema.
The edema varied greatly in degree and extension.
Although mostly confined to the hind legs it may
involve other parts of the body, and even attain a
most severe generalized distribution. It was found
due to malformations of the lymphatic system which
were general in character in all animals irrespective
the grade in their edema. Parallel to the grade of
edema however, these lymphvascular abnormalities
varied from minor hypoplasia and localized aplasia to
a complete agenesis of the whole lymphatic system.
