Tinea pedis(Athlete’s Foot)
- It is the term used for a dermatophyte infection of the soles of the feet and the interdigital spaces.
- The fungal infection is called athlete’s foot because it’s commonly seen in athletes.
- Tinea pedis is most commonly caused by Trichophyton rubrum.
- Using enzymes called keratinases, dermatophyte fungi invade the superficial keratin of the skin, and the infection remains limited to this layer. Dermatophyte cell walls also contain mannans, which can inhibit the body’s immune response.
- Commonly, tinea pedis patients describe pruritic, scaly soles and, often, painful fissures between the toes. Less often, patients describe vesicular or ulcerative lesions.
- A hot, humid, tropical environment and prolonged use of occlusive footwear, with the resulting complications of hyperhidrosis and maceration, are risk factors for all types of tinea pedis. Certain activities, such as swimming and communal bathing, may also increase the risk of infection.
