title: Woringer-Kolopp disease: pagetoid reticulosis.
abstract: A typical clinical and histologic case of so-called 'pagetoid reticulosis' or Woringer-Kolopp disease is reported. This is a chronic cutaneous condition usually with a single focus or at most with a few patches confined to a circumscribed region. A disseminated form has been described as Dupont-Vandaele type, but its relationship to the classic Woringer-Kolopp disease is uncertain. The nosological location of pagetoid reticulosis has not been established, but there are reasons to regard it as a particular and well-defined entity. In relation to the nature of this condition and to the origin of the 'pagetoid cells', it is tempting to consider the possibility that Woringer-Kolopp disease might be a lymphoproliferative epidermotropic disorder, classifiable as a benign form of 'cutaneous T-cell lymphoma', but the early histologic changes are rather indicative of an epidermal origin.
