Dermatophyte infection in ichthyosis vulgaris.

A 31-year-old male who had been suffering from ichthyosis vulgaris developed hyperkeratosic lesions on the palms and soles and ungual alterations of both hands and feet. These lesions were resistant to topical corticosteroid and emollient cream treatments and were found to be caused by Trichophyton rubrum. Association of ichthyosis vulgaris and dermatophytosis--both very common disorders--is to our knowledge a very rare event.
