Assessment of palmar subcutaneous tissue vascularization in patients with Dupuytren’s contracture

Figure 2 Transverse paraffin sections of palmar fascia perforating arteries from Dupuytren’s contracture patients. A: Almost normal structure of perforating artery; B: Adventitial fibrosis, constriction of media and deformity of artery lumen; C: Artery with thick neointimal layer; D: The same artery with breakdown of internal elastic laminae evident due to specific elastin staining (dark brown); E: Extreme lumen narrowing due to neointimal thickening; F: Residual fragments of old internal elastic laminae newly formed elastic fibers in the neointimal layer. Staining: Hematoxylin-eosin (A, B, C, E); Weigert - van Gieson (D, E). Magnification 200 ×.
