Erythrasma is a skin disease that causes brown, scaly skin patches. It is caused by the Gram-positive bacterium Corynebacterium minutissimum. It is prevalent among diabetics and the obese, and in warm climates; it is worsened by wearing occlusive clothing.

Signs and symptoms

The patches of erythrasma are initially pink, but progress quickly to become brown and scaly (as skin starts to shed), which are classically sharply demarcated. Erythrasmic patches are typically found in intertriginous areas (skin fold areas - e.g. armpit, groin, under breast). The slightly webbed spaces between toes (or other body region skin folds) can be involved, making it difficult to distinguish from various Tinea. The patient is commonly otherwise asymptomatic. The diagnosis can be made on the clinical picture alone. However, a simple side-room investigation with a Wood's lamp is additionally useful in diagnosing erythrasma.^[1] The ultraviolet light of a Wood's lamp causes the organism to fluoresce a coral red color, differentiating it from other bacterial infections and other skin conditions. (fungal infections will also be fluorescent)

Treatment

Erythrasma is treated with topical fusidic acid, or systemic macrolides (erythromycin or azithromycin).

Effective treatment of erythrasma-associated inflammation and pruritus with isoconazole nitrate and diflucortolone valerate combination therapy.

Piergiorgio M.Author information Istituto Clinico San Siro, Milan, Italy. dermapier@gmail.comAbstractA warm and moist environment is a common risk factor for erythrasma, a condition characterized by pruritic, scaly and erythematous tan patches on the skin. Here we report on a 13-year-old athletic student presenting with pruritus and mild burning on her left medial thigh, and subsequently diagnosed with erythrasma. The patient was successfully treated with a 5-day regimen of Travocort cream containing isoconazole nitrate 1% and diflucortolone valerate 0.1%.
