Abstract

Objective: To research the formative mechanism of eosinophilic lymphogranuloma (ELG), investigate its essence, provide morphologic base for treatment.
Methods: The biopsies and surgical specimens of 41 cases were studied with the light microscope, fluorescein microscope, electron microscope and immunohistochemical methods. In these cases, 10 cases levels of serum IgE were measured, it was high level, and 11 cases cured with radiotherapy.
Results: The lesions mainly included proliferation of both lymph tissues and post-capillary venues and formed many new scattered lymph follicles. Marked hyperplasia of plasmocytes and mast cells and diffusible infiltration of eosinophilic granulocytes were observed in tissues. The eosinophilic granulocytes were obviously degranulated. When stained with fiuorescein isothiocyanate (FITC) labeled antiserum lgE, the cells showed yellow-green fluorescence, which showed reticular shape in the germinal center of lymph follicles. The swollen tumor-like masses could disappear with radiotherapy, and the eosinophilic granulocytes count in circulation and level of serum lgE reduced to normal.
Conclusion: The serum IgE is high lever and it is positive reaction in the tissues strongly. It is accord with allergic granuloma. The lymphocytes are allergenic ambocepotor cells, the x-ray can kill them and stop allergenic agent, the illness was recovered.
