title: Woringer-Kolopp disease. A lymphomatoid hypersensitivity reaction.
abstract: We report two cases of unilesional pagetoid reticulosis (Woringer-Kolopp disease). Histopathological, immunohistological, ultrastructural, and genotypic studies showed both lesions to be lymphomatoid hypersensitivity reactions, as characterized by polyclonal proliferations of T-lymphocytes; CD8+ T cytotoxic-suppressor (Tc/s) lymphocytes were predominant in one case, whereas CD4+ T helper (Th) lymphocytes were predominant in the other. The nosology of Woringer-Kolopp disease is discussed.
