Pyoderma gangrenosum in a pregnant patient: A case report and literature review

摘要

Abstract Pyoderma gangrenosum (PG) is a rare ulcerative skin disease that usually starts as a pustular lesion and rapidly progresses to a painful ulcer with undermined violaceous borders. The occurrence of PG during pregnancy is uncommon. We describe a case of a pregnant patient with PG who was diagnosed as having ulcerative colitis after delivery. Obstetricians need to understand the pathogenesis of PG and its associated conditions because it is important to make a proper diagnosis and provide targeted therapy.
