title: [Exfoliatio areata linguae et mucosae oris: a mucous membrane manifestation of psoriasis pustulosa?].
abstract: Lesions of the oral mucosa are frequently described in association with psoriasis, particularly in the pustular type. Controversy surrounds the question whether mucosal lesions can be considered as oral manifestation of psoriasis. Two patients presented with concurrent pustular psoriasis and mucosal lesions with the characteristic picture of geographic tongue. Histopathology of the mucosa showed typical features of psoriasis such as marked acanthosis, clubbing of the rete ridges, focal parakeratosis and neutrophilic infiltrates. There was parallel improvement of the skin and the mucosal lesions with systemic retinoid treatment. On the basis of the histopathological features and the clinical course we favour the hypothesis that geographic tongue is an oral manifestation of pustular psoriasis.
