Pitted keratolysis (also known as "Keratolysis plantare sulcatum,"[1] "Keratoma plantare sulcatum,"[1] and "Ringed keratolysis"[1]) is a non-contagious[citation needed] skin infection that can be caused by wearing tight or restricting footwear and excessive sweating. The infection is characterized by craterlike pits on the surface of the feet and toes, particularly weight bearing areas. Treatment consists of the application of topical antibiotics. Pitted Keratolysis is caused by bacteria,[2] which thrive in these environments.[3]

The condition is fairly common, especially in military where wet shoes/boots are worn for extended period of time without removing/cleaning. Skin biopsy specimens are not usually utilized, as the diagnosis of pitted keratolysis is often made by visual examination and recognition of the characteristic odor. Wood lamp examination results are inconsistent.


Pitted keratolysis was first named "Keratoma plantare sulcatum."[4]:268

It was first described in India but has worldwide distribution.[citation needed]
