Erosio interdigitalis blastomycetica is a rare cutaneous condition that is characterized by erosions and macerations of the third web space of the hands and feet. It is caused by the yeast-like fungus Candida, specifically Candida albicans.

Etiology

The condition is caused by the overgrowth of Candida albicans, a type of yeast that is normally present on the skin. The overgrowth can occur due to a variety of factors, including immunosuppression, diabetes mellitus, and prolonged exposure to water or moisture.

Clinical Presentation

Patients with erosio interdigitalis blastomycetica typically present with macerations and erosions in the third web space of the hands and feet. The affected area may be red, swollen, and tender, and there may be a white, cheesy discharge. The condition is often mistaken for tinea pedis or athlete's foot, but it can be distinguished by the absence of scaling and the presence of satellite pustules.

Diagnosis

Diagnosis of erosio interdigitalis blastomycetica is typically made based on the clinical presentation and confirmed by laboratory testing. This may include a KOH preparation to visualize the yeast cells under a microscope, or a culture to identify the specific species of Candida.

Treatment

Treatment for erosio interdigitalis blastomycetica typically involves the use of topical or oral antifungal medications. Topical treatments may include clotrimazole or miconazole, while oral treatments may include fluconazole or itraconazole. In severe cases, or in patients with underlying immunosuppression, systemic antifungal therapy may be required.

Prognosis

With appropriate treatment, the prognosis for erosio interdigitalis blastomycetica is generally good. However, recurrence is common, particularly in patients with underlying risk factors such as diabetes or immunosuppression.
