Exanthematic type of pustular psoriasis consisting of two types of pustular lesion.
A 35-year-old female developed generalized pustules within a short period of time. Clinically, two distinct types of pustules were observed, viz. erythematous patches studded with crops of small pustules, and isolated large pustules with a red halo. Histologically, the former were subcorneal spongiform pustules, whereas the latter were unilocular pustules involving the hair follicular infundibulum or a subcorneal unilocular pustule on the palmo-plantar skin. On the basis of the sudden appearance of the pustules without any pre-existing lesions of psoriasis and the histological findings of the spongiform pustules, we made a diagnosis of the exanthematic type of pustular psoriasis. The lesions responded in a dose-dependent fashion to oral cyclosporin.
