Vessels in the superficial layer of lymph nodes

2021.05.24 note

The anatomical textbooks currently in use do not describe the blood vessels running on the surface of the lymph nodes.

This animation shows a lymph node of a C57BL/6J mouse.

The blood in the inner vessels flows into the surface vessels. [1]

Without proper knowledge of lymph node metastasis, we may misinterpret it.
