A case of impetigo herpetiformis with atypical skin manifestation

Impetigo herpetiformis is a rare and acute pustular eruption that is often accompanied by fever and leukocytosis, which occurs during the 3rd trimester of pregnancy and usually resolves after delivery. In general, impetigo herpetiformis is regarded as a variant of psoriasis that has histopathologic features of pustular psoriasis. The lesions typically begin in the flexural areas, but rarely involve the mucous membranes. The face, palms, and soles are commonly spared. However, we report a 29-year-old woman with impetigo herpetiformis showing mucosal, face and palm involvement, atypical skin manifestation.
