Gross, histomorphological and histochemical changes in the thyroid gland of goat with age. III. Occurrence of thymic tissue.

ABSTRACT

The observations on the thyroid glands from 26 goats aged between 20 days and about 5 years revealed the presence of thymic tissue embedded within or in close vicinity of thyroid in 26.9% of the animals, generally occurring in association with parathyroid tissue (23.08%) and only occasionaly (3.84%) alone. Different forms of the thymic tissue associated to thyroid and variations in their histomorphology and PAS reaction in relation to age has been observed and discussed.
