A report is presented of electron microscope investigation results of biopsy lymph nodes showing the histopathological aspects of the Piringer Kuchinka lymphadenitis, taken from patients with parasitologically ascertained toxoplasmosis of the lymph nodes. The main achievement of this research were: the ultrastructural characterization of cytological features of the follicular reactive centers, both in regard to the reticular and lymphoplasmacellular component, and likewise of the epithelioid cell micronodules with respect to the pleomorphic aspects of activated reticular cells; the definition of the exact nature of heterogeneous structures grouped under the heading of 'toxolike' formations. The salient fact to emerge is the direct morphological demonstration of toxoplasma organisms within the biopsy material (lymph node tissue) and in circulating blood during the peak phase of the titer curve in the dye test.
