Candida – Erosio interdigitalis Blastomycetica
Erosio Interdigitalis Blastomycetica (EIB) is essentially Candida, a yeast, that has infected the finger or toe webs, which I see on a daily basis in both my Woodlands dermatology and Conroe dermatology offices. The areas between the fingers and toes are subject to constant friction and the occlusion of two skin surfaces adjacent to one another promotes sweating. This environment is a perfect habitat for Candida to flourish. On the hands, the third web space is the most common area affected between the 3rd and 4th fingers as the ring on the 4th finger can predispose to extra irritation. On the feet, the 4th web space is most common. Patients with diabetes and those whose hands and feet are frequently immersed in wet environments are most commonly affected. The crux of treatment involves drying out these areas and using a topical antifungal cream twice a day such as Lotrimin cream or ketoconazole cream. Domeboro soaks can also be used to dry out the macerated skin.
