Erythrasma is a type of skin infection caused by the bacterium Corynebacterium minutissimum. This condition is characterized by irregularly shaped pink patches that darken and scale over time. Erythrasma is more common in warm climates and in individuals with diabetes.
Causes[edit]
Erythrasma is caused by the bacterium Corynebacterium minutissimum. This bacterium is part of the normal skin flora, especially in intertriginous areas. The condition is triggered when the bacterium proliferates in warm, moist environments.
Symptoms[edit]
The primary symptom of erythrasma is the presence of irregularly shaped patches on the skin. These patches are initially pink, but darken to a brown color over time. The patches may also scale and have well-defined borders. The most common areas affected are the armpits, groin, and skin folds.
Diagnosis[edit]
Erythrasma is typically diagnosed through a physical examination and a review of the patient's medical history. The doctor may also use a Wood's lamp, which emits ultraviolet light, to examine the skin. The patches of erythrasma will fluoresce a coral-red color under the lamp.
Treatment[edit]
The treatment for erythrasma typically involves the use of topical or oral antibiotics. Topical erythromycin or clindamycin are commonly used. In severe cases, oral antibiotics such as erythromycin or tetracycline may be prescribed.
Prevention[edit]
Prevention of erythrasma primarily involves maintaining good hygiene and keeping the skin dry. It is also important to manage underlying conditions such as diabetes that can increase the risk of developing erythrasma.
