Pitted Keratolysis

Pitted Keratolysis, also known as Keratolysis plantare sulcatum, Keratoma plantare sulcatum, and Ringed Keratolysis, is a bacterial skin infection that typically affects the soles of the feet and toes. It is characterized by small, craterlike pits, especially in weight-bearing areas of the feet.

Pitted Keratolysis on the sole of a foot

Characteristics

• The infection presents as craterlike pits on the sole of the feet and toes.
• These pits are typically located in weight-bearing areas.

Causes

• Pitted Keratolysis is caused by Corynebacterium species bacteria and Kytococcus sedentarius.
• These bacteria thrive in moist environments, making the feet a common site of infection.

Risk Factors

• Excessive sweating of the feet (hyperhidrosis) and the use of occlusive footwear create a favorable environment for these bacteria.
• Individuals who wear closed shoes for extended periods, especially in hot and humid conditions, are at higher risk.

Symptoms

• Aside from the appearance of pits, symptoms can include a foul odor.
• There may also be mild itching or pain associated with the condition.

Diagnosis

• Diagnosis is primarily clinical, based on the appearance of the feet.
• A skin scraping or culture may be performed to confirm the presence of the causative bacteria.

Treatment

• Treatment includes topical antibiotics such as erythromycin or clindamycin.
• Managing foot hygiene, such as keeping the feet dry and using breathable footwear, is crucial.

Prevention

• Preventative measures include good foot hygiene, using antiperspirants, and avoiding occlusive footwear.
• Changing socks regularly and using moisture-wicking materials can also help.
