Abstract
We describe a 31-year-old woman who developed scaly erythemas with pustules all over her body and as well as suffering from fever and general malaise. The histopathological findings revealed subcorneal pustules with acanthosis. We diagnosed this case as generalized pustular psoriasis. She was treated with a topical application of corticosteroids, and later with PUVA therapy. The topical corticosteroids were not effective but the PUVA succesfully improved her cutaneous lesions. Our literature survey in the last decade disclosed 110 cases of generalized pustular pusoriasis, 5 cases of generalized type of acrodermatitis continua (generalized type) and 39 cases of impetigo herpetiformis. Some cases which were reported as generalized pustular psoriasis, however, could also have been diagnosed as acrodermatitis continua (generalized type), or as impetigo herpetiformis, suggesting that these clinical entities cannot be completely distinguished from each other.
