摘要:

ABSTRACTA 14‐year‐old girl was visiting Karuizawa when a tick attached itself to her right upper chest. A purple‐red lesion was induced near the base of the neck. In the center of it, small black particles, the remains of the tick, were present. The tick was identified as an adult femaleIxodes ovatus.Light microscopy: In the dermis near the area where the tick had attached itself, perivascular and periadnexal cellular infiltrations were observed, mainly lymphocytes and neutrophils.Scanning electron microscopy: Parts of the capitulum could be observed on the surface of the skin. The hypostome with its sharp denticles had been inserted from above through the epidermis into the dermis. A cement‐like substance, suggesting a secretion, was observed on the dorsal hypostome. An intactIxodes ovatuswas also examined by scanning electron microscopy for comparison.The present study has probably produced the very first clear visual demonstration of the tick's secretion flow pattern and effect on the surrounding
