Not only is this an aesthetically unappealing condition, but there is evidence to support that disciform erythrasma can be an early sign of type 2 diabetes mellitus.

The generalized erythrasma is most commonly seen in type 2 diabetes mellitus where the lesions go beyond the areas of the body where skin is rubbing together.

The presence of erythrasma is approximately 4% and is more likely to be found in the subtropical and tropical areas compared to the rest of the world.

Lesions of erythrasma are initially pink, but progress quickly to become brown and scaly (as skin starts to shed), which are sharply distinguished.

The most common is interdigital erythrasma, which is of the foot, and may present as a scaling, fissuring, and chronic non-resolving break down of the toe web interspaces.

[3] The slightly webbed spaces between toes, or other body region skin folds, make it difficult to distinguish from various Tinea.

The differential diagnosis for erythrasma includes psoriasis, candidiasis, dermatophytosis, acanthosis nigricans, intertrigo, and many other skin conditions.

Corynebacterium minutissimum is the bacterium that causes this infection, often club-shaped rods when observed under a microscope following a staining procedure, which is a result of snapping division which makes them look like a picket fence.

Initial treatments for minor erythrasma can begin with keeping the area clean and dry and with antibacterial soaps.

The next level is treated with topical fusidic acid and an antibacterial solution such as clindamycin to eradicate the bacteria.
