neoplasm
• evidence of invasion, including clusters of epithelial cells in the mesenchyme and vasculature and loss of the smooth muscle around ducts, is seen associated with high-grade PIN, indicating transition to invasive cancer
• prostates at 6 months of age show multiple, widely spaced areas with low-grade PIN and occasional ducts with high-grade PIN
• at 12-14 months of age, about 50% of ducts show low-grade PIN and about 15% show high-grade PIN compared to 5-10% of control ducts showing PIN
• ductal lumens are filled with atypical and dysplastic cells that distort the overall ductal architecture and are associated with areas of necrosis and abnormal intraepithelial vessels typical of high-grade PIN
