How is erythrasma diagnosed?

The diagnosis of erythrasma can be confirmed through observing coral-pink fluorescence during Wood lamp examination of the affected skin. Porphyrins, predominantly coproporphyrin III, made by Corynebacteria are the origin of this distinguishing fluorescence.

What does erythrasma look like?

Erythrasma looks like a patch of pink to red, scaly skin. The border of erythrasma is well-defined, meaning there is a sharp border between the affected patch and the surrounding normal skin. Over time, the pink or red color fades to tan or brown.

Why does erythrasma fluoresce in a Wood lamp?

The cause of this color fluorescence has been attributed to excess coproporphyrin III synthesis by these organisms, which accumulates in cutaneous tissue and emits a coral-red fluorescence when exposed to a Wood light. [ 32] Under Wood lamp examination, the porphyrins produced by the bacteria fluoresce with a coral pink color.

What makes erythrasma grow in the folds of the skin?

Erythrasma is caused by the Corynebacterium minutissimum bacteria. The bacteria normally live on the skin and can grow in warm, moist areas. That’s why it’s commonly found in folds of the skin.

If in doubt, the doctor may use a specialized ultraviolet light, known as a Wood’s lamp, which will cause the bacteria to fluoresce in a coral-pink color. 4  A Wood’s lamp can only help diagnose certain infections but may differentiate erythrasma from other skin conditions.

What are the side effects of taking erythrasma?

Side effects may include rash, redness, drying, itching, and nausea. Serious infection may require oral antibiotics, including clarithromycin, erythromycin, tetracycline, and chloramphenicol . 5  Treatment may require as little as a single dose (for clarithromycin) or up to a five-day course (for erythromycin).
