The overall architecture of the swine lymphnode was studied on: nodes injected for the visualization of the lymph pathway, serially sectioned nodes, and material processed for scanning electron microscopy. Despite the commonly reported scheme of the node architecture, cortical-like and medullar-like tissue appeared to be intermingled seemingly with no rules in the node substance. Thus it was not uncommon to find cortical-like tissue in a peripheral position like in other mammals. A scheme of the node organization is proposed and the features of the different components of the parenchyma are described with particular emphasis on the lymphatic sinuses and the lymph pathway. Finally, scanning electron microscopical data on swine nodes are discussed and comparison made with observations reported for other mammals.

Abstract
The overall architecture of the swine lymphnode was studied on: nodes injected for the visualization of the lymph pathway, serially sectioned nodes, and material processed for scanning electron microscopy. Despite the commonly reported scheme of the node architecture, cortical-like and medullar-like tissue appeared to be intermingled seemingly with no rules in the node substance. Thus it was not uncommon to find cortical-like tissue in a peripheral position like in other mammals. A scheme of the node organization is proposed and the features of the different components of the parenchyma are described with particular emphasis on the lymphatic sinuses and the lymph pathway. Finally, scanning electron microscopical data on swine nodes are discussed and comparison made with observations reported for other mammals.
