Key takeaways
What does this expanding rash image show?
This clinical photograph shows erythema migrans on a thigh approximately eight weeks after initial presentation. The earlier rash looked less typical.
Does every Lyme rash develop this way?
No. Timing, colour, shape and visibility vary. Some never form a clear ring, and ordinary bite reactions can look similar.
If a rash is expanding after possible tick exposure, obtain appropriate medical advice promptly.
