Bullous Impetigo and Pregnancy: Case Report and Review of Blistering Conditions in Pregnancy

Eight years ago, a case study was conducted on a pregnant woman who developed bullous impetigo, a condition caused by the release of exfoliative toxins type A and B from Staphylococcus aureus, resulting in easily ruptured blisters in the upper layers of the skin. The woman, who was 7 weeks pregnant and allergic to penicillin, developed flaccid, easily rupturing pustules on her lower abdomen, suprapubic region, perineum, buttocks, and proximal legs. These pustules developed into superficial annular erosions with peripheral scale and central healing. A bacterial culture isolated methicillin-susceptible S. aureus. After treatment with clindamycin, all of the lesions resolved. The study concluded that bullous impetigo should be considered in the differential diagnosis of common skin diseases presenting as blisters in pregnant women.
