What is pitted keratolysis?

 
 

Pitted keratolysis is a skin condition that affects the soles of the feet, and is characterized by small, shallow pits or depressions in the skin. This condition is caused by a bacterial infection of the skin, which can lead to a foul odor and can be quite uncomfortable for the affected individual.

The primary cause of pitted keratolysis is a bacterium known as Corynebacterium minutissimum. This bacterium thrives in warm, moist environments, and is commonly found on the soles of the feet, especially in individuals who sweat heavily. When the bacteria infect the skin, they produce enzymes that break down the keratin in the outer layer of skin, leading to the formation of pits or depressions.

Pitted keratolysis is more common in individuals who wear tight, non-breathable shoes, such as those made of rubber or plastic. It is also more prevalent in individuals who have a history of athlete’s foot or other fungal infections of the feet.

Symptoms of pitted keratolysis may include the formation of small, shallow pits or depressions on the soles of the feet, along with a foul odor. The pits may also become white or gray in color, and may be surrounded by a ring of pink or red skin. In some cases, the affected skin may become itchy or painful, and may crack or peel.

Treatment for pitted keratolysis typically involves keeping the feet clean and dry, and wearing shoes that allow the feet to breathe. Antibacterial creams or ointments may also be prescribed to help clear up the infection, along with oral antibiotics in more severe cases. In some cases, a doctor may recommend the use of an antiperspirant on the feet to help reduce sweating and keep the feet dry.

Prevention is key when it comes to pitted keratolysis. This can be achieved by practicing good hygiene, including washing the feet regularly and thoroughly, and keeping them dry. Wearing breathable shoes and changing socks frequently can also help prevent the growth of bacteria on the feet.
