Age distribution.
<p>(a) Black: age at diagnosis of primary melanoma (n = 149). (b) Grey: age at detection of brain metastasis (n = 193).</p
Human melanoma lymph node metastases (entirely embedded).
<p>(A) Box plot comparison of lymphatic vessels (number of D2–40 positive vessels per core) in primary versus metastatic melanoma. * One case, * two cases. (B) Absence of D2–40 staining within metastatic tissue showing no lymphatic vessels (×30). (C) D2–40 positivity shows dilated lymphatic vessels present at the tumor/lymphatic parenchyma interface (arrow, ×150). (D) CD34 staining shows important blood micro-neovascularisation within metastases. (×50). (E) CD34-positive blood microvessels (arrowhead) associated with CD34–negative cells showing vascular mimicry (arrow, ×400). (F) and (G) Cells of vascular mimicries embedded in a PAS (F) and collagen IV (G) positive laminina (arrow, ×320)).</p
