title: Chronic active Epstein-Barr virus infection with giant coronary aneurysms.
abstract: Chronic active Epstein-Barr virus infection (CAEBV) is a nonfamilial syndrome that shows a specific immunodeficiency for the Epstein-Barr virus (EBV). Prolonged fever, hepatosplenomegaly, lymphadenopathy, and liver dysfunction were seen in CAEBV, but cardiac complications are rare. An autopsy case of CAEBV with giant coronary aneurysms and aortic aneurysms is reported. The patient was a 5-year-old Japanese girl. At autopsy, the heart weighed 110 g, and bilateral coronary aneurysms were found. Microscopic studies revealed lymphoid vasculitis of coronary arteries, coronary venules, and aortic arteries. Immunohistochemically, infiltrating small lymphocytes were positive for CD3, CD45RO(UCHL-1), CD43(DF-T1). The presence of EBV in most of these T lymphocytes was proven by in situ hybridization using an EBV-encoded RNA-1 (EBER1) probe. To the best of the author's knowledge, pathology of aneurysms caused by lymphoid vasculitis in CAEBV has not been reported until now.
