72 Page 33 - Rinderpest Microscopic Lesions Epithelial necrosis starts in the stratum spinosum just above the basal layer and extends to the surface. Occasionally there may be syncytial cell formation in this area. When the necrotic epithelium sloughs off, an erosion is formed-erosion because the basal layer is still intact.
Tonsilar crypts are a good place to find syncytial cells.
Lymph nodes-There is disappearance of mature lymphocytes and necrosis of lymph follicles. There may be syncytial cells in the necrotic follicles. Spleen - There is necrosis of lymph follicles.
