<unk>  (also known as<unk>  plantare sulcatum, Keratoma plantare sulcatum, and Ringed<unk>  is a bacterial skin infection of the foot. The infection is characterized by craterlike pits on the sole of the feet and toes, particularly weight bearing areas. The infection is caused by Corynebacterium species bacteria and Kytococcus sedentarius. Excessive sweating of the feet and use of occlusive footwear provide an environment in which these bacteria thrive and therefore increase the risk of developing<unk> . The condition is fairly common, especially in the military where wet shoes/boots are worn for extended periods of time without removing/cleaning. Skin biopsy specimens are not usually utilized, as the diagnosis of<unk>  is often made by visual examination and recognition of the characteristic odor. Wood's lamp examination results are inconsistent. Treatment of<unk>  requires the application of antibiotics to the skin such as benzoyl peroxide, clindamycin, erythromycin, fusidic acid, or mupirocin. Prevention efforts aim to keep the feet dry by using moisture-wicking shoes and socks as well as antiperspirants.
