The one of Virchow can give a positive Troisier's sign when palpated above the clavicle. Blood enters through high endothelia
The one of Virchow can give a positive Troisier's sign when palpated above the clavicle. Blood enters through high endothelial venules, or HEV's, and exits from its hilum. Certain cells pass from the HEV's to the paracortex, then from there to the cortex, which contains secondary follicles consisting of a mantle zone surrounding a germinal center. Entry of pathogens through the skin results in plasma cell differentiation and T cell maturation inside it. Subcapsular sinuses provide the entry point for a fluid that is filtered by macrophages. FTP identify this collection of small bean-shaped structures that filter blood plasma, and whose swelling is often indicative of metastatic cancer.
