title: The definition of Trichophyton rubrum syndrome.
abstract: Although chronic widespread dermatophyte infection is reported widely in the literature, neither a uniform nomenclature, nor even a clear definition of this syndrome have been established so far. Thus, we suggest Trichophyton rubrum syndrome (TRS) for denomination and define the following obligatory clinical and mycological criteria for TRS. (A) Skin lesions at the following four sites: (1) feet, often involving soles; (2) hands, often involving palms; (3) nails; and (4) at least one lesion in another location than (1) (2) or (3), except for groins. (B) Positive microscopic analyses of potassium hydroxide preparations of skin scrapings in all four locations. (C) Identification of Trichophyton rubrum by cell culture at three of the four locations at least. For diagnosis of TRS the criteria (A) and (B) and (C) have to be fulfilled. This standardization is a prerequisite for further investigations of underlying mechanisms of this disease. The typical clinical pattern of TRS is illustrated by the presentation of two paradigmatic cases.
