A Case of Tick Bite Caused by Haemaphysalis flava / 대한피부과학회지

ABSTRACT

We report a case of tick bite caused by Haemaphysalis flava which have never been reported in Korean medical literature. An 31-year-old woman had a asymptomatic erythematous indurated plaque with central crust by tick bite on the left upper back. A excisional biopsy specimen from the skin lesion showed eosinophilic degeneration with thrombosed blood vessels and dense inflammatory cells infiltration mainly composed of eosinophils in the reticular dermis. We could identify this causative tick as Hamaphysalis flava by using the scanning electron microscopic examination.
