Abstract:
Annular pustular psoriasis(APP) is a rare variant of the generalized pustular psoriasis characterized by subacute onset of annular lesion with peripheral advancing pustules. Histologically, it is characterized by spongiform and/or subcorneal pustules which are also found in subcorneal pustular dermatosis(SPD). SPD is very difficult to differentiate from APP, although SPD is thought to be a separate and distinctive entity because of its clinical appearance, characteristic histology, and response to dapsone. We herein report a case of APP showing clinical and histologic features of SPD developed in a patient who had a history of generalized pustular psoriasis.
