Impetigo herpetiformis: menstrual exacerbations for 7 years postpartum

Abstract

Impetigo herpetiformis (IH) is a rare pustular dermatosis that shares striking clinical and histological similarities to generalized pustular psoriasis. The case of a 26-year-old primigravida with IH progressing in the 30th week of her pregnancy is presented. The peculiarity of our presentation relies on the reappearance of the disease postpartum. Monthly exacerbations during menstruation lasted for 7 years. Some probable clues regarding the pathogenesis of IH are suggested.
