A late-stage skin manifestation of Lyme disease caused by Borrelia burgdorferi infection.

Treatment:
Long-term antibiotic therapy, typically oral doxycycline or intravenous ceftriaxone.

Medications:
Doxycycline (a tetracycline antibiotic) or ceftriaxone (a cephalosporin antibiotic). Both are antimicrobial agents.

Prevalence: How common the health condition is within a specific population.
Rare; occurs in late stages of untreated or inadequately treated Lyme disease, particularly in Europe.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Previous untreated Lyme disease, living in or visiting tick-endemic areas, delayed diagnosis of early Lyme disease.

Prognosis: The expected outcome or course of the condition over time.
Good if treated early, but prolonged or irreversible skin changes may occur in advanced cases.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic skin changes, peripheral neuropathy, and persistent Lyme disease symptoms in untreated cases.
