Erythromelalgia misdiagnosed as cellulitis.

This case report examines the presentation of a patient with erythromelalgia that was misdiagnosed as cellulitis on several prior occasions. The presentation of bilateral acral edema and erythema, especially in the setting of myeloproliferative and/or connective tissue diseases, should alert the physician to the possibility of alternate diagnoses, including erythromelalgia. Treatments target symptom alleviation, as well as diagnosis and treatment of causative factors.
