[Paraptic eczema. Why a new name?].

The new term "paraptic eczema" is proposed for a well-defined type of eczema that is elicited by the haematogenous action of an antigen that has already initiated a sensitization of the T-cell-mediated type by topical action on the skin. The term is composed of the Greek words "para" = " beyond, beside" and hapsis = "contact". Many other names have been used in the past to describe partial aspects of paraptic eczema, such as "haematogenous contact eczema", "dyshidrotic eczema", "pompholyx", "dermatophytid", or "tylotic palmar eczema", but these terms are inappropriate for a workable delineation of this nosological entity.
