Pitted keratolysis also known as keratolysis sulcata, is a bacterial infection or foot skin infection of the soles of the feet or, less commonly, the palms of the hands. The most common result is identified by very smelly feet due to the soles infection. Usually the heel or forefoot become white with clusters of punched-out pits or small holes in feet.

Pitted Keratolysis bacterial infection

Pitted Keratolysis is generally caused by Coryneform bacteria, though several other strains of bacteria have been discovered in the lesions, including Micrococcus sedentarius, Actinomyces keratolytica and Dermatophilus congolensis. The tell-tale crater-like pitting is a direct result of the proteolytic enzymes manufactured by the bacteria digesting the keratin, which is a resilient protein that gives the skin its strength and toughness.
It is also important to note that pitting keratolysis is non-contagious. Check out for some other most common foot problems along with braces one can shop in dealing with various infections.

Pitted keratolysis is one of the reasons for very smelly feet. It is described by whitish skin and bunches of punched-out pits or small holes in skin feet. The microscopic organisms multiply in wet conditions. The setting is because of annihilation of the horny cells (stratum corneum) by protease compounds created by the microscopic organisms. The terrible stench is because of sulfur mixes created by the microscopic organisms: thiols, sulfides and thioesters. Click here for pitted keratolysis pictures and more.

Causes of Pitted Keratolysis

Pitted Keratolysis is caused by a few bacterial animal types, including corynebacteria, Dermatophilus congolensis, Kytococcus sedentarius, actinomyces and streptomyces. The microorganisms multiply in damp conditions. The setting is because of pulverization of the horny cells (stratum corneum) by protease proteins delivered by the microscopic organisms. The terrible stench is because of sulfur mixes delivered by the microbes: thiols, sulfides and thioesters.

Diagnosis of Pitted Keratolysis:

In the event that you think you have pitted keratolysis, see a specialist. You will require anti-toxins to treat the disease. To determine you to have pitted keratolysis, your doctor will swab the region or accomplish something many refer to as a skin scratching, where your doctor acquires an example of skin to check for microbes and parasites under a magnifying lens.

Skin scrapings are regularly taken to reject fungal infection. Wood light examination shows a trademark coral red fluorescence now and again. The diagnosis is once in a while made by skin biopsy uncovering characteristic histopathological highlights of pitted keratolysis.

In most cases, the classic appearance and presentation of the pitted lesions and white spots on the feet is proof enough to confidently diagnose pitted keratolysis. There is also the distinctive and unpleasant smell that this disorder is associated with. If there is any doubt, gram’s staining of the scraping, along with a culture of the scraped material, can aid in reaching a definitive diagnosis.

It is necessary to differentiate between pitted keratolysis and plantar warts or athlete’s foot. Plantar warts typically present with localized areas of hyperkeratosis, which is thickening of the outer layer of the skin, and are very often painful. Athlete’s foot presents with itching between the toes not limited to pressure-bearing areas of the foot.

Who’s At Risk

People of any age, race, or sex can fall victim to this disorder, though it is more commonly found in men. People who sweat or wash excessively tend to be prone to pitted keratolysis. The prolonged wearing of occlusive footwear, such as tight shoes or rubber boots, also makes one more susceptible. Not surprisingly, athletes and soldiers are extremely prone to this problem. Hot and humid weather is another factor for raising the risk. Those on immunosuppressive drug therapy or diabetes sufferers are also more likely to succumb to pitted keratolysis.

Pitted keratolysis is much more common in males than in females. Occupations at risk include:

  • Athletes
  • Sailors or fishermen
  • Industrial workers
  • Military personnel
  • Agriculturist
  • Females offering pedicure and foot mind in a spa salon may likewise be influenced by pitted keratolysis.



Learn some of the common techniques for the prevention of pitted keratolysis.

The single most crucial preventative step in avoiding this skin disease is treating excessive sweating of the palms of the hands or the soles of the feet. Wearing 100% cotton socks helps keep feet drier, drastically reducing the chances of developing pitted keratolysis. Airy shoes like sandals or open-toed shoes are also recommended. No matter what the style of the shoe, it should not be too snug, as tight, closed-in shoes are the ideal breeding spot for pitted kerotolysis. The importance of early treatment to prevent episodes of reoccurrence cannot be stressed enough. Many experts also claim that it is wise to replace your shoes after a course of treatment, limiting the chances of re-infection. Anti-fungal and anti-bacterial dusting powders have also proven to be effective weapons against the occurrence or relapse of this condition.


Bacterial Infection
Pitted keratolysis is a skin issue described by crateriform setting that fundamentally influences the weight bearing parts of the plantar surface of the feet and, sometimes, the palms of the hand as collarettes of scale. The indications of pitted keratolysis are expected to a shallow cutaneous bacterial disease.

Pitted keratolysis has experienced a few name changes. Its was portrayed at first in the mid-1900s as keratoma plantare sulcatum, a sign of yaws. It was distinguished in the 1930s as a one of a kind separate clinical element, and the name was changed to keratolysis plantare sulcatum. The present name, pitted keratolysis, depicts the clinical introduction well and has remained the cutting edge classification to portray this element.


Elements Prompting The Advancement of Pitted Keratolysis Include:

  • Sweltering, sticky climate
  • Occlusive footwear, for example, elastic boots or vinyl shoes
  • Over the top sweating of hands and feet (hyperhidrosis)
  • Thickened skin of palms and soles (keratoderma)
  • Diabetes mellitus
  • Propelled age
  • Immunodeficiency


By What Means Can Pitted Keratolysis Be Anticipated

It will rapidly repeat unless the feet are kept dry. The accompanying safety measures ought to be taken to avoid repeats:

  • Wear boots for as short a period as would be prudent
  • Wear socks which viably ingest sweat, ie cotton or potentially fleece
  • Wear open-toed shoes at whatever point conceivable
  • Wash feet with cleanser or germicide chemical twice day by day
  • Apply antiperspirant to the feet no less than twice week after week
  • Try not to wear similar shoes two days in succession — dry them out
  • Try not to impart footwear or towels to others.
  • Wear boots for as short a period as could be expected under the circumstances
  • Wear socks which viably retain sweat i.e. cotton or potentially fleece
  • Wear open-toed shoes at whatever point conceivable
  • Wash feet with cleanser or disinfectant chemical twice every day
  • Apply antiperspirant to the feet no less than twice week after week
  • Try not to wear similar shoes two days in succession – dry them out
