Not Another Presentation of Cellulitis: A Case Report of Erythromelalgia
Cellulitis is among the more common conditions diagnosed and treated within pediatric emergency departments. However, unusual distribution, recurrence, and/or poor response to antibiotics may point towards another pathologic process. This case presentation illustrates a teenager with recurrent episodes of painful erythematous and swollen extremities misdiagnosed repeatedly as cellulitis. Careful history, exam, laboratory evaluation and rheumatologist consultation aided in making the correct diagnosis of erythromelalgia, which was successfully treated with supportive measures. This report reviews a rare presentation of erythromelalgia, as well as its pathophysiology, recommended therapies, and common misdiagnoses.
