Impetigo herpetiformis and pustular psoriasis during pregnancy

Abstract

Impetigo herpetiformis and pustular psoriasis during pregnancy are distinct diseases. Pustular psoriasis during pregnancy is indistinguishable clinically, genetically, and histologically from pustular psoriasis in women who are not pregnant. Impetigo herpetiformis is not a heritable disorder and is not found particularly in persons with a personal or family history of psoriasis. Histologically in impetigo herpetiformis there are many large mononuclear cells in the dermis and in epidermal pustules. Proliferation of these mononuclear cells in the dermis is intense.
