Pitted keratolysis is a disease characterized by asymptomatic pits of the stratum corneum. The causative agent is a filamentous organism which has been identified as corynebacterium species. The disease developed in 53% of 387 volunteers whose feet where continually wet for three days or more. Pitted keratolysis was just as common during field trails in the United States as during combat tests in South Vietnam. The high incidence of the disease reported here suggests the entity is more common than the paucity of reports suggest.
