neoplasm
• 100% of males develop prostate tumors
• after the development of epithelial hyperplasia, reactive stromal proliferation develops and then the tumor progresses to high-grade dysplasia with regions of carcinoma in situ, and on occasion, contain cribriform PIN-like lesions and regions of adenocarcinoma
• areas of microglandular patterns mimicking invasive prostate cancer, indicating localized intraprostatic invasion and areas of distinct lymph-vascular space invasion is seen indicating locally invasive carcinoma
• males castrated at 7 weeks of age do not develop prostatic tumors or show prostate regrowth
• tumors regress in males castrated at 11 week of age and androgen treatment restores tumor growth, indicating that tumor growth is androgen-dependent
• cribriform PIN-like lesions (J:48623)
• at 21 weeks, typical prostatic intraepithelial neoplastic lesions (PIN lesions) (J:92562)

reproductive system
• stromal cell hyperplasia is observed at 21 weeks
• males exhibit massive enlargement of the prostate gland by 21 weeks
• clusters of hyperplastic epithelial cells in the prostate are first seen around 5 weeks of age
• between 8 and 10 weeks of age, the epithelium of the dorsolateral prostate is completely replaced by hyperplasia and surrounded by a deep layer of proliferating stroma; the stromal cells eventually fill in the interstitial space
• the dorsolateral and anterior lobes show the most dramatic changes and the ventral lobe remains small but shows evidence of epithelial cell hyperplasia
