Erythromelalgia (C0014804)

Definition (NCI) A rare disorder characterized by periodic inflammation and blockage of the vessels of the extremities, resulting in skin redness, swelling, and burning pain in the affected sites. It may manifest as a primary disorder caused by mutations of the SCN9A gene or as a secondary disorder due to hematologic disorders or medication side effects.
Definition (MSH) A peripheral arterial disease that is characterized by the triad of ERYTHEMA, burning PAIN, and increased SKIN TEMPERATURE of the extremities (or red, painful extremities). Erythromelalgia may be classified as primary or idiopathic, familial or non-familial. Secondary erythromelalgia is associated with other diseases, the most common being MYELOPROLIFERATIVE DISORDERS.
