Although words like lymphocyte, lymph node, lymph, and lymphatic vessels are common in daily medical activities, Lymphology has always been considered as a sort of younger sister to Angiology or Phlebology. Also, apart from few pioneer physicians, it has never been investigated as a discreet, well identified area of research.

Therefore, the following “Dictionary” aims to be a sort of metaphorical “window” on the extensive and still poorly explored world of lymphatic diseases, as well as to provide some useful, basic information for a correct diagnosis of patients affected by lymphatic-lymph node disorders.

Questo “Dizionario” vuole, quindi, rappresentare una sorta di metaforica “finestra” sul vasto ed ancora poco inesplorato mondo della patologia linfatica e fornire utili elementi di conoscenza di base per una corretta diagnosi e gestione del paziente affetto da alterazioni del sistema linfatico-linfonoidale.


From a chemical point of view, BPV is a monosodium salt in methanol used in lymphology as a stain for in vivo detection of lymphatic structures. Owing to its chemical composition, it has a remarkable tropism for lymphatics and, when injected into the tissues, it is almost completely drained through all major lymphatic collectors and structures. It is excreted by the kidneys. In some individuals, it may cause allergic reactions.


Benzopyrones are a heterogeneous group of chemical substances mostly of plant origin, with a basic structure consisting of a benzenic ring, where an oxygen molecule replaces a carbon one. There are two main classes of benzopyrones: alpha-pyrones (coumarins) and gamma-pyrones (diosmin, hesperidin, rutin).


They are short-stretch bandages containing a paste of zinc oxide and other active substances (natural coumarins, glycerol, calcium chloride, etc.). They are employed in the treatment of venous disorders – e.g. in postphlebitic syndrome – or in lymphatic disorders, for example in acute and chronic lymphangitis, in particular owing to their anti-inflammatory, antibacterial, exudate-absorbing activity, hence for their trophic effect on tissues involved by irritative-dystrophic processes.
