What illness causes cracked feet in summer?
In summer, when the feet develop cracks, it is necessary to be alert for fungal infections. A common disease is hyperkeratotic tinea pedis, which is a skin disease caused by fungal infection. It can lead to thickening of the stratum corneum and decrease in moisture, resulting in dryness and cracking. At this time, anti-fungal drugs should be used promptly for treatment, and attention should be paid to skin care.
Fissures in summer feet are likely to be hyperkeratotic tinea pedis, a fungal skin disease caused by dermatophyte infection of the feet. As dermatophytes mainly invade the stratum corneum of the skin, they can cause thickening of the stratum corneum and lack of moisture. The thicker it is, the easier it is to crack, manifesting as excessive keratinization, roughness, and anhidrosis of the foot skin. Most skin lesions are located on the heel. In addition, the plantar surface and the sides of the feet may also be affected, and in severe cases, even the entire plantar surface can be involved.
For vesicular tinea pedis, foot powder can be used to soak the feet, followed by topical application of compound benzoic acid ointment. For squamous hyperkeratotic tinea pedis, terbinafine hydrochloride cream and urea ointment can be alternately used. For macerated erosive tinea pedis, a 1:5000 potassium permanganate solution can be used for cold compresses, followed by topical application of miconazole nitrate ointment.
