Lymphatic dysplasia in paediatrics. A new classification

A classification of dysplasias of the lymphatic system is proposed on the basis of the anatomical structures involved: lymph vessel-angiodysplasia, lymphadeno(nodal)-dysplasia and the summary of both lymphangio-adeno(nodal)dysplasias. The suggested terminology is: LAD I (Lymphangiodysplasias), LAD II (Lymphadeno(nodal)dysplasia) and LAAD (lymphadeno(nodal)-dysplasia). With this classification we may coherently group the malformations we already know, relate them to the big syndromes and to all the other angiodysplasias and also create the reference background for another chapter of lymphology: primary or idiopathic lymphedema.
