DefinitionThis section has been translated automatically.

Tinea cruris describes a, mostly chronic dermatophyte infection of the lower legs (in the Anglo-American linguistic usage it is called Tinea corporis). The clinical picture is characterised by the duration of the infection, the immunological and local initial situation of the patient and the type of pathogen.

EtiopathogenesisThis section has been translated automatically.

Autoinoculation by shaving the hairs of the legs in case of pre-existing tinea unguium or tinea pedum. Traumatisation leads to follicular ruptures and dislocation of infected keratin particles into the dermis. From these dislocated keratin particles the "keratinophilic" dermatophytes draw their food reservoir.

ManifestationThis section has been translated automatically.

Especially women are affected.

LocalizationThis section has been translated automatically.

Distal lower leg exteriors.

Clinical featuresThis section has been translated automatically.

Brownish to blue-reddish, pea-sized, follicularly bound, itchy, possibly confluent nodules with scaly ruffled edges.

DiagnosisThis section has been translated automatically.

Fungal detection in native preparation or culture. S.a.u. Mycoses.

Differential diagnosisThis section has been translated automatically.

Note(s)This section has been translated automatically.
