Diagnosis 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.


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.
