Malpighian corpuscles of spleen in infancy and childhood.

ABSTRACT

In early infancy splenic white pulp is seen arranged around the central arterioles. They do not show any reactive changes even in the presence of systemic infections. Lymphoid follicles are seen at 6 weeks of life. Germinal centres appear from the 8th week of life onwards. Periarteriolar lymphocytic sheaths persist in the older children along with the reactive changes.
