Abstract
- Background We examined the vascularity of mammary Paget disease histologically to confirm the increased blood flow observed previously by clinical imaging. The relationships among blood vessel density (BVD), histopathological parameters of blood flow in the nipple, and the expression of angiogenic factors such as basic fibroblast growth factor (bFGF) and vascular endothelial growth factor A (VEGFA) were examined. Methods We calculated the average CD34-positive BVD and podoplanin (D2–40)-positive lymphatic vessel density (LVD) and the proportion of proliferating of endothelial cells in 14 Paget disease, 3 dermatitis biopsy, and 14 age-matched control cases. As a parameter related to blood flow in the nipple, the total CD34-positive blood vessel lumen area relative to the entire nipple area was measured in each Paget disease and control case using an automated image analysis system. Immunohistochemical expression of bFGF and VEGFA in Paget cells was also examined. Results The average BVD and LVD were significantly higher in the Paget disease cases than in the dermatitis (p = 0.003) and control (p p = 0.003). The average BVD was correlated with the average LVD (r = 0.734, p r = 0.692, p p = 0.003) and control (p r = 0.818, p r = 0.503, p = 0.006). Conclusion These results provide direct histopathological evidence of a marked increase in nipple blood flow in Paget disease detected by clinical imaging. bFGF is considered to play a pivotal role in angiogenesis in mammary Paget disease.
