Erythromelalgia is a rare clinical syndrome characterized by erythema, increased temperature, and severe burning pain that can be aggravated by warmth or relieved by cold. Erythromelalgia occurs either as a primary, idiopathic form, or secondary to a number of diseases and conditions. Although fairly well studied in adults, the characteristics, pathogenesis, and natural history are poorly characterized in the pediatric age group. Different therapeutic options have been tried, but no optimal treatment has been suggested for erythromelalgia. We report a rare case of linear erythromelalgia in a 12-year-old girl involving her central body from the peripheral extremities, which seemed to be secondary due to vasculitis. Clinical progress waxed and waned on maintenance aspirin and propranolol.

Erythromelalgia is a rare neurovascular pain syndrome characterized by a triad of redness, increased temperature, and burning pain primarily in the extremities. Erythromelalgia can present as a primary or secondary form, and secondary erythromelalgia associated with a myeloproliferative disease such as essential thrombocythemia often responds dramatically to aspirin therapy, as in the present case. Herein, we describe a typical case of a 48-year-old woman with secondary erythromelalgia linked to essential thrombocythemia in the unilateral hand. As this case demonstrates, detecting and visualizing the hyperthermal area through infrared thermography of an erythromelalgic patient can assist in diagnosing the patient, assessing the therapeutic results, and understanding the disease course of erythromelalgia.
