During the past five years increasing attention has been devoted to the study of dermatoses of the palms and soles which resemble ringworm infections but which are not mycotic. In 1928, Mitchell1reported a series of cases. The previous year Barber and Eyre,2Dore3and Roxburgh4—all in England—published papers dealing with similar disorders. In 1929, Lehmann5presented before this section several cases of pompholyx and emphasized the importance of internal disturbances in them. Barber6clarified the meaning of the term acrodermatitis continua and called attention to the fact that it is the same disorder that was described as dermatitis repens by Crocker; he also described the generalized eruptions which may develop from the localized form of the disease. He has shown that these conditions are infective and are due to Staphylococcus aureus, and that this group should be regarded as chronic pyogenic dermatitis.
