Figure Lengend Snippet: A. Liver: Encapsulated hepatocellular carcinoma was highly necrotic and focally calcified (Haematoxylin-eosin). B. Lung: Papillary adenocarcinoma. (Haematoxylin-eosin). C. Macroscopical changes in liver (box shows the area of the microscopical sections in F–H). D. Macroscopical changes in spleen, control spleen on the left (microscopical sections in I–K). E. Macroscopical changes in paratubarian area (microscopical sections in L–N). F. Cavernous hemangioma featuring focal hyalinization. G. The same tumor mass area with higher magnification (haematoxylin-eosin). H. Weak focal hVEGF-A 165 immunoreactivity was present in the same area (True Blue as a chromogen), arrows indicate positive cells. I–K. Fibrous scars formed by collagenous and elastic fibres surrounded by dilated cystic spaces, focally filled with blood and revealing inconsistently CD34 positive lining. I. Hematoxylin-eosin. (an arrow points to an area shown in K) J. CD34 immunostaining. K. The same area as in I with higher magnification (stained with Masson Trichrom). Asterix in I and J indicate the same area. L. Cystically dilated paratubarian spaces with signs of old haemorrhage and thrombus formation (marked with *), an open circle points to an area which was highly vascularized as shown in M. (CD31 immunostaining) and a box indicates an area which revealed focal hVEGF-A 165 immunopositivity shown in N. (hVEGF-A 165 immunostaining). Bar : F, I, J - 500 µm, G, H, K - 100 µm, A, B, M, N - 200 µm L - 1000 µm.
Article Snippet: Tissue vascularization was assessed by immunostaining with CD34 antibody (HyCult biotechnology BV, clone MEC 14.7, dilution 1∶20).
