Harderian gland - Hyperplasia in a male B6C3F1 mouse from a chronic study. There is a well-demarcated focus of alveoli that doesn�t compress the adjacent tissue.

Harderian gland - Hyperplasia in a male B6C3F1 mouse from a chronic study (higher magnification of Figure 1) The alveoli in the hyperplastic focus are lined by increased numbers of large cells with enlarged nuclei and a slightly different tinctorial quality than surrounding normal cells.

Harderian gland - Hyperplasia in a male F344\N rat from a chronic study. This hyperplastic focus (arrow) consists of a small cluster of alveoli lined by increased numbers of well-differentiated cells crowded into multiple layers.
