Histopathological findings of the lymph nodes. a Irregular paracortical areas of coagulative necrosis with abundant karyorrhectic debris and distortion of the nodal architecture (hematoxylin and eosin stain, original magnification Ă—20; scale bar = 1mm). b Areas of paracortical hyperplasia with small and large lymphoid cells (hematoxylin and eosin stain, original magnification Ă—40; scale bar = 200 μm). c Extensive paracortical area of coagulative necrosis with different types of histiocytes and lymphocytes at the margins of the necrotic areas (hematoxylin and eosin stain, original magnification Ă—100; scale bar = 200 μm). d The karyorrhectic foci formed by different cellular types, predominantly histiocytes, plasmacytoid monocytes, and small and larger lymphocytes (hematoxylin and eosin stain, original magnification Ă—200; scale bar = 100 μm)
