Electron microscopy was used to study the epidermis in cases of tinea cruris due to infection by Trichophyton rubrum . Keratinocytes in the epidermis showed various degenerative features ranging from focal cell damage to whole cell necrosis. Two types of alterations, the diffuse loss of electron density in the cytoplasm and the reticular appearance of the cells, are presumably ultrastructural counterparts of intracellular edema. Intercellular edema appeared simultaneously with intracellular edema. Cells infiltrating the epidermis consisted mainly of neutrophilic leucocytes. There were no signs of close apposition of Langerhans cells to mononuclear cells. From these findings it is thought that alterations of the epidermis in tinea cruris can be classified as non‐specific degeneration possibly induced by toxic causes. Some information regarding the fine structures of hyphae and arthrospores living in the horny layer as parasites was also obtained.
