Tinea pedis in Child
The clinical presentation of tinea pedis may vary. The webspaces and soles are affected most frequently, but the condition may spread to involve the nonplantar surfaces of the foot as well. Interdigital maceration, especially of the lateral toe webs, is commonly seen. Tinea pedis is frequently asymmetric with one foot only being affected or disease being more widespread on one foot than the other. The degree of associated pruritus varies, but most cases are asymptomatic. Trichophyton rubrum may present with a red, scaly, moccasin-like plaque involving the sole. The bullous form of tinea pedis is rare in children and is usually caused by Trichophyton interdigitale (formerly T. mentagrophytes var. interdigitale). Onychomycosis may be associated.
A dermatophytid reaction (also called an "id reaction") is a hypersensitivity process that can occur secondary to tinea pedis. The condition manifests on the lateral aspects of the fingers and may mimic dyshidrotic dermatitis. This hypersensitivity process will resolve with adequate treatment of the dermatophyte infection.

6020002 – Tinea pedis
- Webspace erythrasma is typically hyperkeratotic but can be erosive.
- Bullous tinea pedis may be confused with friction blisters or autoimmune blistering disorders.
- Maceration with mixed bacteria (mixed toe web infection)
- Dyshidrotic dermatitis (also called dyshidrotic eczema or pompholyx)
- Contact dermatitis (irritant, allergic)
- Juvenile plantar dermatosis
- Palmoplantar keratoderma
- Pitted keratolysis – A frequently overlooked condition that causes plantar pits and malodorous feet. Its cause is bacterial, and it responds to topical antibacterials such as clindamycin solution and aluminum chloride 20% solution for drying.
