title: Dermatitis repens, Lapière and generalized pustular psoriasis.
abstract: The presence of subcorneal pustules in a solitary, indolent, crusted plaque, or in erythema annulare-like lesions with a trailing scale, is evidence of atypical psoriasis. When these lesions appear late in life there is a significant risk of generalized pustular psoriasis with a poor prognosis. A case is presented in whom both of these atypical forms occurred and who developed severe generalized disease. Clinical and histological features are described.
