White pulp is a histological region of the spleen. 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.
