[Chronic autoimmune thrombocytopenia in the spleen and microparticles as seen in scanning electron microscopy].
In chronic autoimmune thrombocytopenia numerous round formations in the sinus lining cells are observed by scanning electron microscopy. They occur sometimes on the surface of erythrocytes passing through the sinus wall. It is possible that they are not cytoplasmic processes but platelet microparticles sticking on the surfaces of various cells. These particles are too small in routine counting of blood platelets in the light microscopy and probably too fragile in examining in transmission electron microscopy.
