Plantar pitting, pitted keratolysis, ringed keratolysis, Keratoma plantaris sulcatum.
Pit-shaped corneal defects on the stressed areas of the soles of the feet.
- Occurring worldwide
- Frequently among men
- Sports shoe wearers are particularly affected
- Hardly ever seen in patients >50 years
- Especially in tropical and subtropical climate zones
- The disease does not occur in cold climates and is not observed in people walking barefoot in dry climates
- Frequent association with erythema sulcatum and erythrasma
- Especially corynebacteria, Micrococcus sedentarius, Dermatophilus congolensis, Actinomyces spp., Dermatophilus congolensis
- The onset is mainly caused by hyperhidrosis and occlusive footwear. In a warm and humid environment, the proliferation of the above-mentioned bacteria occurs, which are part of the normal skin flora. Damage to the horny layer and enzymatic activity of protease and keratinase lead to the formation of shallow pits.
- Whitish, skin-coloured as if punched out, circular pits on the pressure-loaded areas of the sole of the foot. No or little pain under pressure, but patients sometimes report pain when walking
- Mostly foetider smell (Bromidrosis) and hyperhidrosis
Soles of the feet, especially the pressure-loaded areas.
Circumscribed defects of the stratum corneum. Sometimes bacteria can be detected.
If environmental factors can be eliminated, the prognosis is favourable, otherwise a chronic course threatens.
- Trigger remediation
- Treatment of hyperhidrosis
- Regular washing of the feet with disinfectant solutions
- Hygiene measures!
- No occlusive footwear, wear breathable shoes
- Erythromycin cream 2-3x daily
- Clindamycin cream 2-3x daily
- Clotrimazole cream 2-3x daily
- Benzoyl peroxide as cream, gel or solution 1x daily
