Dermatophytoses are generally painless and are not life-threatening. Tinea pedis or athlete's foot Contrary to the name, tinea pedis does not solely affect athletes. Tinea pedis affects men more than women, and is uncommon in children. Even in developed countries, tinea pedis is one of the most common superficial skin infections by fungi. The infection can be seen between toes (interdigital pattern) and may spread to the sole of the foot in a "moccasin" pattern. In some cases, the infection may progress into a "vesiculobullous pattern" in which small, fluid-filled blisters are present. The lesions may be accompanied by peeling, maceration (peeling due to moisture), and itching. Later stages of tinea pedis might include hyperkeratosis (thickened skin) of the soles, as well as bacterial infection (by streptococcus and staphylococcus) or cellulitis due to fissures developing between the toes. Another implication of tinea pedis, especially for older adults or those with vascular disease, diabetes mellitus, or nail trauma, is onychomycosis of the toenails. Nails become thick, discolored, and brittle, and often onycholysis (painless separation of nail from nail bed) occurs. Tinea cruris or jock itch More commonly occurs in men than women. Tinea cruris may be exacerbated by sweat and tight clothing (hence the term "jock itch"). Frequently, the feet are also involved. The theory is that the feet get infected first from contact with the ground. The fungus spores are carried to the groin from scratching from putting on underclothing or pants. The infection frequently extends from the groin to the perianal skin and gluteal cleft. The rashes appear red, scaly, and pustular, and is often accompanied by itch. Tinea cruris should be differentiated from other similar dermal conditions such as intertriginous candidiasis, erythrasma, and psoriasis. Tinea corporis or ringworm of the body Lesions appear as round, red, scaly, patches with well-defined, raised edges, often with a central clearing and very itchy (usually on trunk, limbs, and also in other body parts). The lesions can be confused with contact dermatitis, eczema, and psoriasis. Tinea faciei or facial ringworm Round or ring shaped red patches may occur on non-bearded areas of the face. This type of dermatophytosis can have a subtle appearance, sometimes known as "tine incognito". It can be misdiagnosed for other conditions like psoriasis, discoid lupus, etc. and might be aggravated by treatment with immunosuppressive topical steroid creams. Tinea capitis or scalp ("blackdot") ringworm Children from ages 3-7 are
