Clinical InformationClinical

  • Parapsoriasis

    the term applied to a group of relatively uncommon inflammatory, maculopapular, scaly eruptions of unknown etiology and resistant to conventional treatment. eruptions are both psoriatic and lichenoid in appearance, but the diseases are distinct from psoriasis, lichen planus, or other recognized dermatoses. proposed nomenclature divides parapsoriasis into two distinct subgroups, pityriasis lichenoides and parapsoriasis en plaques (small- and large-plaque parapsoriasis).

  • Pityriasis Lichenoides

    a subgroup of parapsoriasis itself divided into acute and chronic forms. the acute form is characterized by the abrupt onset of a generalized, reddish-brown, maculopapular eruption. lesions may be vesicular, hemorrhagic, crusted, or necrotic. histologically the disease is characterized by epidermal necrolysis. the chronic form shows milder skin changes with necrosis.

  • Large Plaque Parapsoriasis|Parapsoriasis en Plaques

    a variant of parapsoriasis in which the plaques are large.

  • Parapsoriasis

    an inflammatory skin disorder of unknown etiology characterized by papules and plaques or scaly patches resembling psoriasis.

    a rare condition that stimulated chronic radiodermatitis. it is considered a variant of mycosis fungoides.

  • Small Plaque Parapsoriasis

    a variant of parapsoriasis in which the plaques are small.
