Scalp ringworm in children may be caused by anthropophilic fungi such as Trichophyton tonsurans, which is spreading in cities in the United Kingdom, or Microsporum audouinii. Sporadic cases are caused by M.canis which is acquired from cats or dogs. In all cases there is itching, hair loss, and some degree of inflammation which is worse with M. canis infections.
Kerion, an inflamed, boggy, pustular lesion, is often due to cattle ringworm and is fairly common in rural areas. It is often seen in children in the autumn when the cows are brought inside for the winter.
Tinea incognito is the term used for unrecognised fungal infection in patients treated with steroids (topical or systemic). The normal response to infection (leading to erythema, scaling, a raised margin, and itching) is diminished, particularly with local steroid creams or ointments. The infecting organism flourishes, however, because of the host's impaired immune response—shown by the enlarging, persistent skin lesions. The groins, hands, and face are sites where this is most likely to occur.
Seborrhoeic dermatitis of adults may also be caused by Malassezia.
