Fatal Severe Fever with Thrombocytopenia Syndrome: An Autopsy Case Report.

Unlabelled: As of June 2014, among six patients who had severe fever with thrombocytopenia syndrome (SFTS) at our hospital, an 83-year-old man died despite receiving appropriate critical care. An autopsy revealed extensive ischemic damage of the intra-abdominal organs, including the liver, spleen, stomach and gut, due to severe celiac atherosclerotic stenosis and superior mesenteric arterial thrombosis. Many SFTS virus nucleoprotein antigen-immunoreactive cells were detected in a paraaortic node, where necrotizing lymphadenitis was seen, and in the spleen.
