Reply to: “Facial erythromelalgia?”

To the Editor: A few predominantly facial cases of potential erythromelalgia have been described, but these appear to be exceedingly rare.1-4 In 1 of the case reports, the condition was mistaken for other dermatologic conditions (rosacea and contact dermatitis) for years until the patient developed symptoms of erythromelalgia elsewhere.1 Another case report highlights the importance of keeping this in the differential diagnosis to avoid confusion with dermatologic connective tissue disorders that involve the face.
