109,113,114) In kidney and liver, adenoviral infection is often associated with parenchymal necrosis, microabscess formation, or even granulomatous inflammation, and nuclear inclusions may be apparent on hematoxylin-eosin-stained sections, (109,113-115) described as large nuclei with basophilic inclusions and a thin rim of cytoplasm.
The inflammatory process has a distinctly granulomatous pattern, characterized by the presence of foreign-body-type giant cells (multiple irregularly shaped nuclei in abundant cytoplasm) (figure 2, A), chronic inflammatory cells (mature lymphocytes and plasma cells), and microabscess formation (figure 2, B); the latter is made up of acute inflammatory cells (neutrophils with three or four lobes to the nuclei surrounded by granularcytoplasm).
