Comments

The parents found a tick behind the ear of this 27-month-old girl one week before she was evaluated in the office for a equivocal low grade fever and widely disseminated annular red plaques. The tick was tested with PCR and found to be negative for the DNA of Borelia burgdorfi. However, the following week serologic tests were positive for Lyme disease (both IgG and IgM). She was treated with oral amoxacillin, and the eruption cleared in 2 days.
