Abstract:
Three-dimensional (3D) visualisation of microscopic structures provides useful information about their configuration and the spatial (hence functional) relationship between different components in tissues. This paper describes 3D dynamic reconstructions of the pre-lymphatic labyrinth in two cases of "normal" breast core biopsies and one case of pseudoangiomatous stromal hyperplasia. Direct anastomoses between pre-lymphatic channels and true lymphatics of the breast were demonstrated. It is concluded that pre-lymphatics are a way of communication between breast epithelial/stromal structures and the main lymphatic system. The present findings suggest that the existence of pre-lymphatics has to be taken in consideration in the intramammary spread of malignant tumours.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
Lymphatic Vessels and Lymph Transport
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular spaces.
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
