The altered coat of the arterioles, consisting of [[adenoid]] tissue, presents here and there thickenings of a spheroidal shape, the '''white pulp''' ('''Malpighian bodies of the spleen''', '''splenic lymphoid nodules''').
These bodies vary in size from about 0.25 mm. to 1 mm. in diameter.
They are merely local expansions or [[hyperplasia]] of the adenoid tissue, of which the external coat of the smaller arteries of the [[spleen]] is formed.
They are most frequently found surrounding the [[arteriole]], which thus seems to tunnel them, but occasionally they grow from one side of the vessel only, and present the appearance of a sessile bud growing from the [[arterial wall]].
