Pitted keratolysis

Pitted keratolysis is a condition of the skin that affects the soles of the feet and sometimes the palm. It is a bacterial infection that is caused mainly by coryneform bacteria but there are other strains of bacteria that can cause this condition but to a lesser extent.

Common indications of pitted keratolysis include the formation of bunches of miniature perforated pits and foul smell coming from the soles of the feet as well as lesions that appear on any region of the feet.

The bacteria generate an enzyme that eats keratin which is a protein found in the upper skin layer. This will cause the development of groups of superficial craters. The condition is common among people who sweat more and those who wear tight shoes. It usually affects the sole of the foot which is always wet due to contact with water or perspiration.

Pitted keratolysis is not a contagious disease. The bad smell on the soles of foot is caused by sulphur compounds that are produced by the bacteria. Sweating excessively and those who have diabetes are susceptible to develop this condition.
