Three patients presented to our clinic with erythrasma. The results of the clinical examination of each patient showed bilateral patches of erythema in the plicae inguinalis with minimal fine scaling and no central clearing. One patient also had a small superficial erosion in the right plica inguinalis. The results of an examination using Wood light showed coral red fluorescence in each patient. Potassium hydroxide preparations were negative for hyphae or yeast and bacterial cultures grew normal skin flora.

Traditionally, erythrasma has been treated with oral erythromycin or various topical regimens. Single-dose clarithromycin holds the potential to be a safe, cost-effective, well-tolerated alternative to a more lengthy course of erythromycin.
