Worldwide spread. Prevalence (Central Europe): In about 4-6% of the population. Common in tropical climate zones (20% of the population)
EtiopathogenesisThis section has been translated automatically.
ManifestationThis section has been translated automatically.
m:f=1:1; 30-50 years (average: 44.6 years)
LocalizationThis section has been translated automatically.
Mainly intertriginous areas: axillae (70-80%), scrotum, inguinal region, large labia, inner thigh, submammary.
Clinical featuresThis section has been translated automatically.
Initially, preferably in the warm season, individual, 5.0-10.0 cm large, yellow-brown to reddish-brown, sharply defined, symptomless spots form, which confluent with increasing disease duration. Later flat plaques with fine scaling appear. Lesional itching can occur during longer periods of time and is intensified by sweating.
Frequently accompanying bromhidrosis.
DiagnosisThis section has been translated automatically.
Wood light examination (320-400nm): coral red fluorescence of the infested areas.
Differential diagnosisThis section has been translated automatically.
TherapyThis section has been translated automatically.
Notice! Acid soaps, milieu sanitation. In stubborn cases, shave the affected areas. No fatty ointments. The patient should be informed that the hyperpigmentation may persist for several weeks after the pathogens have been removed!
External therapyThis section has been translated automatically.
Due to the progressive development of resistance (also with topical antibiotics), creams containing azole or ciclopirox should be preferred (e.g. bifonazole cream, ciclopirox cream). The application is usually carried out daily for one week, then if necessary 1x/week as prophylaxis.
Also important: Sanitation of the local millieu, thorough daily skin cleansing with water and (acid) syndets. If necessary, therapy control in the Wood light.
Internal therapyThis section has been translated automatically.
Progression/forecastThis section has been translated automatically.
Favorable, frequent recurrences. Residual pigmentation often remains.
