Adrenal Gland - Hyperplasia - Gallery

Image of hyperplasia in the adrenal gland cortex from a male Sprague-Dawley rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a male Sprague-Dawley rat from a chronic study. There are two adjacent foci of hyperplasia (H) in the zona fasciculata.
Image of hyperplasia in the adrenal gland cortex from a male Sprague-Dawley rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a male Sprague-Dawley rat from a chronic study (higher magnification of Figure 1). The foci of hyperplasia (H) are rounded, circumscribed areas of increased cellularity.
Image of hyperplasia in the adrenal gland cortex from a female Sprague-Dawley rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a female Sprague-Dawley rat from a chronic study. There is a circumscribed but noncompressive focus of hyperplasia (H) in the zona fasciculata.
Image of hyperplasia in the adrenal gland cortex from a female Sprague-Dawley rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a female Sprague-Dawley rat from a chronic study (higher magnification of Figure 3). The cells in this hyperplastic lesion (H) are smaller and more closely packed than those in the adjacent normal cortex.
Image of hyperplasia in the adrenal gland cortex from a female F344/N rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a female F344/N rat from a chronic study. There is a hyperplastic lesion (H) in which cortical cells are increased in number but are smaller in size than adjacent normal cortical cells (NC).
Image of hyperplasia in the adrenal gland medulla from a female F344/N rat in a chronic study
Adrenal gland, Cortex - Hyperplasia in a female F344/N rat from a chronic study. The hyperplastic lesion (H) has an increased number of cells that are smaller than adjacent normal cortical cells (NC).
Image of hyperplasia in the adrenal gland medulla from a male B6C3F1/N mouse in a chronic study
Adrenal gland, Medulla - Hyperplasia in a male B6C3F1/N mouse from a chronic study. There is a small, noncompressive focus of hyperplastic medullary cells at the corticomedullary junction (arrow). M = medulla.
Image of hyperplasia in the adrenal gland medulla from a male B6C3F1/N mouse in a chronic study
Adrenal gland, Medulla - Hyperplasia in a male B6C3F1/N mouse from a chronic study (higher magnification of Figure 1). The hyperplastic cells (arrow) are increased in number but are smaller and more basophilic than adjacent normal medullary cells (M).
Image of hyperplasia in the adrenal gland medulla from a male F344/N rat in a chronic study
Adrenal gland, Medulla - Hyperplasia in a male F344/N rat from a chronic study. There is focal hyperplasia (arrow) deep in the medulla (M).
Image of hyperplasia in the adrenal gland medulla from a male F344/N rat in a chronic study
Adrenal gland, Medulla - Hyperplasia in a male F344/N rat from a chronic study (higher magnification of Figure 9). The hyperplastic cells (H) are smaller (so the nuclei appear more crowded) and more basophilic than the adjacent normal medullary cells (M).
