A 9-year-old girl presents with a 1-week history of painful, erythematous nodules on the anterior shins. She had a sore throat 2 weeks ago. The lesions are tender, raised, and warm. Chest X-ray is normal. What is the most likely diagnosis?
- A Erythema induration of Bazin
- B Erythema nodosum ✓
- C Superficial thrombophlebitis
- D Nodular vasculitis
Correct answer: B. Erythema nodosum
Explanation
Erythema nodosum presents with painful, erythematous, raised nodules on the anterior shins, often following streptococcal pharyngitis in children. It is a panniculitis that resolves without ulceration. Erythema induration of Bazin is associated with tuberculosis and may ulcerate. Superficial thrombophlebitis presents as a tender cord along a vein. Nodular vasculitis is chronic and often associated with tuberculosis.
