Tinea pedis

Tinea pedis

Tinea pedis (commonly known as athlete’s foot) is an acute or chronic dermatosis. Most infections are caused by the Trichophyton species. The patient will present with itching, burning, or stinging. Pain here may indicate secondary infection with complicating cellulitis. Interdigital tinea pedis is the most common predisposing cause of lower extremity cellulitis in healthy individuals. On the sole and heel, tinea may appear as chronic noninflammatory scaling occasionally with thickening or fissuring. This may extend over the sides of the feet in a moccasin distribution. The KOH preparation is usually positive. Tinea pedis can also present as scaling or fissuring in the toe webs with maceration. As the web spaces become more macerated, the KOH preparation and fungal culture have a lower tendency to return positive results because bacterial species begin to dominate. The malady can be treated with aluminum subacetate solution soaks for 20 minutes twice daily. Broad spectrum antifungal creams and solutions will help combat dipheriods and other gram-positive organisms. If topical imidazoles fail, one week of topical allylamine treatment will often result in clearing. Itraconazole (200 mg daily for two weeks or 400 mg daily for one week) can be used in refractory cases. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app
