Mucous membrane involvement in generalized pustular psoriasis: Report of three cases and review of the literature

G. Wagner, J. R. Luckasen and R. W. Goltz

Pustular eruptions on both skin and mucous membranes occur in the various forms of generalized pustular psoriasis. Three patients with generalized pustular psoriasis also had an eruption on the tongue resembling geographic tongue; one patient had sterile conjunctivitis. Histologically, the spongiform pustule of Kogoj is common to lesions of both skin and mucosa. We suggest that generalized pustular psoriasis be considered one of the mucocutaneous syndromes.
