A 12-year-old child presents with a circular, erythematous lesion on the arm with a well-demarcated border and a central clearing. The patient reports recent close contact with teammates after practice. Which of the following treatments would most effectively resolve the lesion?
Rationale
AANP Domain Level: Plan
ANCC Domain Level: Planning
Focus Area: Dermatology
The circular lesion with a well-demarcated border and central clearing, especially following close contact with others, is indicative of a fungal infection. The treatment of choice for tinea corporis (ringworm) is an antifungal like clotrimazole. Hydrocortisone would not address the underlying fungal infection, mupirocin is for bacterial infections, and acyclovir is for viral conditions.
Study Tip:
Tinea corporis often presents as a circular lesion with central clearing, and antifungal treatments like clotrimazole are the first-line therapy. Avoid corticosteroids for fungal infections, as they may worsen the condition.
