A rare case of hereditary angioedema with exclusive gastrointestinal symptoms and no cutaneous involvement.

Abstract

We report a case of hereditary angioedema presenting solely with gastrointestinal symptoms, including abdominal pain and bloating. The patient experienced recurrent abdominal pain for 4 years, without any evident clinical features such as skin or mucosal edema. Almost every episode occurred more than 10 days after the conclusion of menstruation. Ultimately, the diagnosis was confirmed through whole-exome sequencing and the evaluation of relevant indicators.
