Not All Erythema Migrans Lesions are Lyme Disease

Lyme disease is the number one arthropod-transmitted disease in the U.S., and one of the diagnostic criteria for the illness is development of an erythematous bull ’s eye rash around a tick bite which may expand over time, hence the term erythema migrans. However, there are other erythema migrans-like rashes such as those from a condition known as southern tick-associated rash illness. This paper describes a patient with an erythema migrans-like lesion simil ar to that associated with Lyme disease, resulting from a bite by a nymphal stage lone star tick, Amblyomma americanum.
