Abstract
A human case of tick bite on the scalp was found at a local hospital on June, 1984. The patient, 63-year old female, was attacked by a tick while working in a farm forest which located in the suburbs of Seoul. The clinical complaint was a (worm) mass on the scalp which she thought as a tumor. On admission the patient complained of facial edema and general malaise. After removal of the mass (tick), small bleeding and discoloration were observed around the biting site. The tick was morphologically examined and identified as Ixodes nipponensis. This is the 4th human case of tick bite reported in the literature of Korea.
