Tinea capitis is the most important superficial fungal condition in children. It is often unrecognised but the presence of alopecia, scale and lymphadenopathy, especially in inner-city children should prompt investigation. An understanding of changing epidemiology and prevalence of causative organisms is important in deciding appropriate therapy. The use of diagnostic aids including dermoscopy is increasing and is reported to be helpful in identifying subtle signs. Trichophyton tonsurans accounts for the majority of cases in the UK and terbinafine is increasingly advocated as a safe and effective therapy. Exclusion from school is unnecessary provided the child is receiving appropriate systemic and topical therapy, but family members should be screened and carriers should receive treatment. Steroids and surgical treatments should be avoided. Treatment failure is common and may be multifactorial. Mycological cure after completing treatment should be sought and therefore follow up is necessary for Tinea capitis cases. Development of molecular diagnostic methods may improve our ability to diagnose Tinea capitis accurately and quickly in the future. Emerging new dermatophytoses affecting other anatomical sites are discussed which, although not common in the UK, may be seen due to increasing travel worldwide.
