Under a moderately-high magnification of 250X, this Wilder’s Reticulin-stained photomicrograph depicts the cytoarchitectural changes found in a liver tissue specimen extracted from a deceased yellow fever patient. This particular view highlights the mid-zone of this lobule, revealing a disassociation in its network of reticular fibers. See PHIL 2176, and 8239, depicting TEMs of the yellow fever virus.
Yellow fever histopathologic diagnostic confirmation is based upon the following cytoarchitectural changes: parenchymal disorganization; midzonal necrosis; acidophilic degeneration; fatty degeneration.
From the booklet entitled, ”Yellow Fever: Positive and Differential Histopathology Diagnosis”, PHIL images 13001 through 13043 illustrate the findings encountered when performing a differential diagnoses comparing characteristics of liver cytoarchitecture in cases of yellow fever with viral hepatitis, Lassa fever, Marburg virus, Ebola virus, Dengue hemorrhagic fever, Congo-Crimean hemorrhagic fever, Rift Valley fever, and malnutrition.
