| Normal and hyperplastic glandular epithelium present in the biopsies was counted as an internal control. |
| A dose-related increase in the incidences of hyperplastic nodules, adenomas and carcinomas was seen. |
| In addition, there was no evidence of any hyperplastic, pre-neoplastic, or neoplastic changes in peripheral blood or lymphoid tissues. |
| The hyperplastic follicular epithelium forms infoldings into the lumen of the follicle, producing a stellate outline. |
| This finding supports the theory that hyperplastic mesothelial cells derive from reactive serosal mesothelium and are dislodged into draining lymphatics. |
| There were also esophageal glycogenic acanthosis and hyperplastic polyposis in the antrum accompanied by Helicobacter pylori-related gastritis. |
