Abstract


The aim of this study is to assess Hassall’s corpuscles in lamb. Thymus samples were harvested from 10 lambs (3 months old) and histologically processed. From the harvested samples, 5 μm seriated sections were made, stained with Goldner’s trichrome method and examined under light microscope. In the medulla of the thymic lobules there are on average 7-8 highly polymorphic Hassall’s corpuscles. The majority of the corpuscles (80%) have a diameter between 5 and 50 μm, 15% between 50 and 100 μm and only 5% have a diameter of over 100 μm. Only 20-25% among them have a typical „onion-like†structure, 40-45% present different keratinization degrees and 3-5% are cavitary corpuscles, containing degenerated cell fragments. Hassall’s corpuscles in lamb are numerous and highly polymorphic.
