The most obvious sign that a person is suffering from pitted keratolysis is its classic appearance. The circular and shallow pits are the calling card of pitted keratolysis. The pits often overlap in places to produce larger areas of erosion. Occasionally these legions present with a green or brown hue around and within the pits. These superficial erosions are found under the toes and on the soles of the feet, and especially at the pressure bearing points such as the heel. Both sides of the foot are usually equally effected.
Signs and Symptoms of Pitted Keratolysis
Pitted keratolysis is often linked to excessive sweating of the palms or soles (palmoplantar hyperhidrosis.) The bacterial digestion of the keratin results in a very foul odor, causing many of its suffers great anxiety, especially in social situations. Thankfully, irritation is generally minimal, though occasionally burning, itching, and soreness are experienced with pitted keratolysis. The appearance of this condition’s characteristic lesions is much more pronounced when the affected area is wet.

Other Symptoms of pitted keratolysis

The outcome is rancid feet, because of contamination of the bottoms. Either the forefoot or the rear area or both wind up white with groups of punched-out pits. The appearance is more sensational when the feet are wet. Rarely, the fingers are comparably influenced. There is a variation of pitted keratolysis where there are more diffuse red regions on the soles.

  • For the most part influences the bottoms, forefoot, the rear area or both. Palms are once in a while contaminated.
  • Results in a whitish skin surface with groups of different, fine punched-out pits.
  • Pits regularly consolidate (combine) to frame bigger, pit like sore.
  • A variation of pitted keratolysis presents with diffuse red territories on the soles.
  • The most usually announced side effect is malodour. The pits themselves are generally asymptomatic however may cause soreness or tingling when strolling.

Several different bacterial species will cause pitted keratolysis; the most common culprits are:

  • Streptomyces
  • Corynebacteria
  • Kytococcus sedentarius
  • Dermatophilus congolensis
  • Actinomyces

These bacteria often multiply in wet or moist conditions. This is why people who don’t let their feet air out enough often develop it.

The bacteria on the feet or palms will produce protease enzymes, which destroy the outermost layer of the epidermis, causing the characteristic pitting. The bad smell is caused by sulfur compounds that are produced by the bacteria on the skin.
