Definition
This section has been translated automatically.

Amiodarone (Amiodarex®, Amiohexal®, Cordarex®, Tachydarone®), an iodinated benzofuran derivative, is a potassium antagonist used as a class III antiarrhthmic agent, particularly for supraventricular and ventricular tachycardia. Dermatologic UAWs include slate-gray dyschromias on light-exposed skin areas.

Occurrence/Epidemiology
This section has been translated automatically.

0.5-10% of patients treated with amiodarone show dose-dependent discoloration. 0.1-0.3% of patients develop full vision.

Etiopathogenesis
This section has been translated automatically.

Phototoxically induced lysosomal storage of lipids, amiodarone and amiodarone metabolites

Manifestation
This section has been translated automatically.

Dose-dependent occurrence (daily dose usually > 400 mg/day) after excessive but also after uniform tanning. Predominantly men are affected.

Localization
This section has been translated automatically.

Areas exposed to light, especially the face (nose, forehead), ears, back of the hand.

Clinical features
This section has been translated automatically.

Usually long latency period of at least 10-12 months between first use of amiodarone and appearance of initial symptoms. Initial erythema in about 30-40% of patients, especially on the face. Later, blue or gray dyschromia in light-exposed areas. Skin folds and furrows are usually excluded.

Histology
This section has been translated automatically.

Plaque-like, perivascular conglomerates of yellow-brown color complexes (lipofuscin) in the upper dermis. The "degeneration pigment" lipofuscin, a protein and cholesterol containing mixture of lipophilic and argentophilic pigments and is taken up by lyosomes and histiocytes. Extracellular pigment does not occur.

Diagnosis
This section has been translated automatically.

Reflected light microscopy: Interfollicular, mostly perivascularly localized bluish or brownish grey pigment streaks and plaques. Widening of the horizontal subepidermal vascular plexus.

General therapy
This section has been translated automatically.

Stopping the triggering medication.

External therapy
This section has been translated automatically.

Avoid direct sunlight, textile and physical/chemical sun protection. Cosmetic covering of hyperpigmentations with tinted covering paste (e.g. R025, Dermacolor).

Progression/forecast
This section has been translated automatically.

Hyperpigmentation is only partially reversible in 50-70% of patients. Restitutio ad integrum (approx. 30% of patients) within a period of 2-4 years after discontinuation of the drug.
