Lymph node toxoplasmosis. Follow-up of 237 histologically diagnosed and serologically verified cases.
The clinical features, histology and follow-up of lymph node toxoplasmosis are presented in the light of 237 histologically and serologically verified cases. Lymph node toxoplasmosis is a disease with mild symptoms, and in most patients the enlarged lymph nodes were the only sign. Three fourths of the patients were women and the majority were under 40 years of age. The clinical picture was not specific, but suggestive features included a relatively short history, presence of the nodes in the neck and relative lymphocytosis in peripheral blood. Histological changes in the lymph nodes were characteristic. The most important features were strong hyperplasia but preserved general structure with small groups of epithelioid cells both in the paracortical area and in the germinal centers. Strands of monocytoid cells were usually found. 80% of the cases with typical histology also had high antibody titers, and in more than 85% of the cases with high antibodies, the lymph nodes presented a typical picture of toxoplasmosis. The follow-up revealed that lymph node toxoplasmosis. The follow-up revealed that lymph node toxoplasmosis is a disease without complications, nor is there any connection with malignant lymphomas.
