A case of severe fever with thrombocytopenia syndrome (SFTS) in which a skin biopsy from the tick‐bite region was analyzed is reported. The patient was a 72‐year‐old woman who developed fever and thrombocytopenia after a tick bite. SFTS was diagnosed from polymerase chain reaction (PCR) analysis of a blood sample. Histopathological analysis of a skin biopsy specimen from the tick‐bite region showed CD20‐positive perivascular and interstitial immunoblastic cells, which were positive to anti‐SFTS virus (SFTSV) nucleoprotein antibody. In addition, SFTSV RNA was detected by real‐time PCR from this biopsy specimen. Moreover, hemophagocytosis was also found in the tick‐bite region. To the best of our knowledge, this is the first report to analyze the details of the tick‐bite region of skin in SFTS, and the first to detect virus‐infected cells in the skin. The present findings may help elucidate the mechanisms of entry of SFTSV.
