Pitied Keratolysis.

Clinical features of 70 cases of pitted keratolysis are described. Bacterial and mycological cultures were done in 20 cases. Sixteen of these (80%) and 7 out of 10 (70%) controls yielded corynebacterium species in culture. The significance of this finding in relation to the aetiology of pitted keratatolysis is discussed. An attempt to reproduce the lesions artificially in 5 healthy volunteers did not succeed.
