bullseye rash
Tick bite sign
A bullseye rash is a circular skin lesion with a distinctive target-like pattern—a red center surrounded by a pale ring, then another red ring.
It's the characteristic early sign of Lyme disease, appearing at the site of a tick bite: The doctor recognized the bullseye rash immediately.
Medically called erythema migrans.
