DefinitionThis section has been translated automatically.
Rare neuro-vascular skin disease and functional circulatory disorder characterized by burning, painful sensations in the acral area of the hands and feet (rare). Characteristic, paroxysmal, painful, seizure-like hyperemia of the acres after exposure to heat.

ClassificationThis section has been translated automatically.
Three forms of erythromelalgia are described:
- Primary autosomal dominant inherited erythromelalgia (erythrothermalgia) provoked by heat and muscle work (OMIM:133020).
- Secondary erythromelalgia
- Secondary erythromelalgia in various haematological diseases
- Secondary erythromelalgia in inflammatory or degenerative vascular diseases (e.g., arterial occlusive disease, thrombophlebitis)
Occurrence/EpidemiologyThis section has been translated automatically.
In Scandinavia, its incidence is estimated at 0.3-0.4/100,000 population.
EtiopathogenesisThis section has been translated automatically.
- In primary erythromelalgia (erythrothermal malgia) an autosomal dominant mutation in the sodium channel coding SCN9A gene (sodium channel, voltage-gated, type 9, alpha subunit) located on chromosome 2q24.3 (OMIM:133020) has been shown to be present (Klein-Weigel PF et al. 2018). This genetic defect leads to a defective function of the voltage-gated sodium channel.
- In the majority of patients a"small-fiber" neuropathy with pathological sudomotor axon reflex was detected. Some (about 25%) have impaired adrenergic function, others (also about 25%) have abnormal cardiovagal function.
- In secondary variants, mostly idiopathic etiology, especially in polycythemia, leukemia (chronic myeloid leukemia), diabetes mellitus, hypercholesterolemia, gout, rheumatoid arthritis, lupus erythematosus, mixed connective tissue disease, Sjögren's syndrome, AIDS, viral infections, syphilis, endangiitis obliterans, chronic perniosis, neurological diseases such as multiple sclerosis or neuropathies.
- In the case of thrombocythemia, the disorders of the cutaneous microcirculation could be explained by the formation of thrombi.
- Associations with the application of drugs such as nifedipine, bromocriptine, norephedrine and nicardipine have been described casuistically.
- Furthermore, in very rare cases, associations with carcinomas of the lung and gastrointestinal system have been described.
- In China, in an endemic form of erythromelalgia, an associated virus, the erythromelalgia-associated poxvirus (ERPV) has been isolated.
ManifestationThis section has been translated automatically.
Equal for women and men; no gender preference. Age of manifestation: 5-6th decade; less frequently in children around 10 years of age (familial form of erythromelagia).
LocalizationThis section has been translated automatically.
Leg feet (90%), hands (20-25%), nose (very rare).
Clinical featuresThis section has been translated automatically.
Intermittent (in larger series, syncopal erythromelalgia occurs in 95% of patients. In 3-5% it is permanent), painful, hyperemic, reddened and swollen skin with increased sensitivity to heat. Often burning pain. During syncope, skin temperature rises 7-8°C, blood flow is increased 10-fold. The seizures can be provoked by raising the temperature of the extremity to an individual "critical thermal point" which is between 32°C and 37°C, and by physical overload. Duration of seizures: minutes to hours. A large proportion of patients present with localized or generalized anhidrosis.
- Seizure-like, uniform redness and swelling of the affected extremities.
- Lesional hyperthermia
- Burning pain of the extremities
- Pain aggravated by heat
- Pain is immediately relieved by cooling (Note: many patients try to relieve the pain by continuous blow-drying or by ice-water baths; this is successful as long as the cooling effect lasts. Prompt recurrence after rewarming).

TherapyThis section has been translated automatically.
Internal therapyThis section has been translated automatically.
- Clomipramine (Anafranil) 100-200 mg/day can be tried.
- Alternatively, long-term therapy with small doses (100 mg/day) of acetylsalicylic acid or with indomethacin. In case of high platelet numbers or platelet dysfunction high doses of ASS.
- Alternative: experiment with high doses of magnesium (e.g. Magnesium Verla) p.o.
- Experimental: Prostaglandin-E1 (Alprostadil), e.g. Caverject i.v., followed by nitroprusside sodium (e.g. Nipruss).
Operative therapieThis section has been translated automatically.
In severe therapy-resistant cases a temporary borderline blockade with local anesthesia is recommended. If the treatment is successful and the autonomic dysregulation is permanently broken through, permanent sympathetic lysis (borderline blockade with alcohol) should then be discussed.
Progression/forecastThis section has been translated automatically.
Note(s)This section has been translated automatically.
- Diagnosis based on the clinic.
- Typically, patients cool their extremities in cold water during a seizure. This results in sudden freedom from symptoms. Recurrence of symptoms when the body warms up. Exclusion of other functional or organic circulatory disorders.
- Possibly capillary microscopy. Search for causes of secondary erythromyalgia.
