Abstract
One full-term, dead foetus was successfully removed from a 5-year old, crossbred
black and white goat. The goat was stall-fed with green fodder and it delivered
two dead foetuses in the previous pregnancy. The foetus had a large swelling in
the cranio-ventral neck region. Upon cutting skin, the swelling revealed
extremely enlarged thyroid gland having two asymmetrical lobes with the right
lobe was 8.10 x 15.0 cm and the left 5.5 x 8.6 cm in size. The skin was devoid
of hair, pale-white and thickened with myxedema. Histologically, the enlarged
thyroid consisted of colloid goitre and the lungs were oedematous. This case of
congenital goitre was unusual and differed from the reported cases in two
aspects viz 1) the two lobes were enlarged but unequal and 2) histologically
goitre was colloid instead of usual hyperplastic type.
