[Diffuse congenital goitre of the thyroid in the kid].

Abstract

The macroscopic and histological appearance is described of diffuse congenital goitre found in two twin kids which were born alive but soon died. The changes described appear to represent an intermediate stage between parenchymatous goitre and colloid goitre, with the latter predominating. Morphological and functional explanations are suggested for the changes observed, with reference to the features of importance in comparative pathology.
