On physical examination, the physician notes a large, erythematous, annular patch with central clearing on her back (Figure 227-1). The patient states that the rash has gotten progressively larger during the last 3 days and she has had a recent onset of intermittent joint pain. She does not recall being bitten by an insect. She denies taking medications within the past month and has no known allergies. When asked about recent travel, she admits to a camping trip in eastern Massachusetts, which she returned from 4 days ago. The patient was diagnosed with Lyme borreliosis and started on doxycycline 100 mg twice daily for 14 days. She responded quickly to the antibiotics and never developed the persistent stage of Lyme disease.
