    Image of follicle epithelium hyperplasia in the thyroid gland from a male B6C3F1 mouse in a chronic study
    Thyroid gland, Follicle, Epithelium - Hyperplasia in a male B6C3F1 mouse from a chronic study. Proliferative projections of hyperplastic epithelium are present in a single follicle (arrow).
