Fungal infection can affect your hair, nails, and skin. Dermatophyte is the main cause of fungal infection. Dermatophytes are a type of fungi with filaments and metabolize keratin which presents in our skin, hair, and nails. There are a few types of dermatophyte infections. They are Tinea corporis, Tinea pedis, Tinea cruris, Tinea capitis, and Tinea unguium. Other types of fungi are Candida albicans, Aspergillus, Candida neoformans, Histoplasma, and many more.

- Tinea corporis is an infection of body surfaces other than the feet, groin, face, scalp hair, or beard
- Tinea cruris is the infection of the groin
- The Tinea pedis is the infection of the foot
- Tinea unguium is the infection of the nails
- Tinea capitis is an infection of the scalp hair
- The Tinea faciei is the infection of the face
- Tinea manuum is the infection of the hand
- The Tinea barbae is the infection of the beard
Tinea pedis or athlete’s foot is the most common fungal infection caused by a dermatophyte. The Tinea pedis usually take place between your toes and it is frequently accompanied by Tinea unguium, Tinea cruris, and tinea manuum. Tinea pedis often affect young men after the age of puberty. The common causative organisms for this condition are Trichophyton rubrum, Trichophyton interdigitale, and Epidermophyton floccosum. Patients usually got the infections via direct contact with the organisms. Walking barefoot on contaminated surfaces is a risk factor for this condition. The clinical features are:
- Red and itchy scales or erosions
- Fissures between toes
- Vesicular lesions
- Bullous lesions
This condition is diagnosed by skin scrapings and test with a potassium hydroxide solution to detect the presence of the causative organism. Gram staining is important if a secondary bacterial infection is suspected. The goals of treatment are:
- Relieve and reduce symptoms
- Reduce the risk of secondary bacterial infection
- Limit the spread of infection to other parts or other people
Topical antifungal is the treatment of choice. However, some patients may need oral antifungal. The example of topical antifungals are azoles, allylamines, butenafine, ciclopirox, tolnaftate, and amorolfine. The examples of oral antifungals are terbinafine, itraconazole, and fluconazole.
Tinea corporis is the skin infection other than the feet, face, groin or hand. The causative organisms are T. rubrum, Trichophyton tonsurans, Microsporum canis, T. interdigitale, Microsporum gypseum, Trichophyton violaceum, and Microsporum audouinii. The clinical features are:
- Round or oval scaling patches or plaque
The test to confirm the diagnosis of Tinea corporis is similar to Tinea pedis. This condition has a very good response to topical antifungals such as azoles, allylamines, butenafine, ciclopirox, and tolnaftate. Oral antifungal is the alternative if topical antifungal fails.
This condition is a dermatophyte infection of the crural fold. The causative organisms are T. rubrum, E. floccosum, and T. interdigitale. The clinical feature is the presence of red and elevated patch on the thigh. The diagnosis can be confirmed with the same test done for Tinea corporis and Tinea pedis. The treatment is similar to Tinea corporis.
