[Diagnostic and differential diagnostic value of cytological findings in toxoplasmic lymphadenitis].

The cytologic investigation of needle biopsy material from lymphomas of unclear genesis may give valuable diagnostic references in patients with lymphadenitis toxoplasmotica. Findings of 19 patients are explained. Suspicious for a toxoplasmogenic genesis are colouredness of the cell picture with large basophilic roundnuclear cells, conspicious macrophagocytosis in reticulum cells and small-focal proliferation of the epitheloid cell. In own material these 3 criteria only 5 times appeared together. Two simultaneously existing, suspicious for Piringer's lymphadenitis findings, were shown in 11 patients. Most frequently was found the coloured picture of the round-nuclear cells (16/19). A conspicuous RHS-phagocytosis was to be observed in 12 smears. In careful clinical and serological controls only in 4 out of 19 patients a histological investigation was necessary. In the cytological findings also other lymphomatous processes must differential-diagnostically be taken into consideration.
