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]]. ==See also== * [[spleen]] * [[lymph node]] * [[marginal zone]] ==External links== * {{BUHistology|07703loa}} * {{eMedicineDictionary|White+pulp}} * {{EmbryologySwiss|qblood/lymphat06}} * {{AnatomyAtlasesMicroscopic|09|174}} - "Spleen: White Pulp splenic nodule" {{anatomy-stub}} {{Gray's}} {{Lymphatic system}} [[Category:Hematology]] [[tl:Puting sapal]]
