Epidermotropic Mycosis Fungoides

To the Editor.—  We have read Dr Lever's case report of "Localized Mycosis Fungoides With Prominent Epidermotropism: Woringer-Kolopp Disease" (Archives 113:1254-1256, 1977) with great interest because of the dearth of information available in the English language on the disorder. Dr Lever correctly credits the French physicians Woringer and Kolopp with the original description of the localized form of this rare variant of mycosis fungoides.We would like to call attention to a long neglected paper that we believe represents the first report of the generalized form of Woringer-Kolopp disease. In 1931 (eight years prior to Woringer and Kolopp's original description), Ketron and Goodman of the Johns Hopkins Medical School reported the case of a 59-year-old bricklayer under the title, "Multiple Lesions of the Skin Apparently of Epithelial Origin Resembling Clinically Mycosis Fungoides."¹ The well-documented histopathologic findings in this case are indistinguishable from what we know today as Woringer-Kolopp disease.
