Hereditary angioedema (HAE) is a syndrome characterized
by episodic swelling of subcutaneous and submucosal tissues, due to a deficiency or dysfunctionality in functional
C1 esterase inhibitor (C1-inh). The authors present a case
of a 40 year-old man with a positive family history of HAE,
recurrent episodes of abdominal pain, nausea and vomiting.
The immunological study revealed low levels of C1-inh and
C4 and normal levels of C1q. Acquired angioedema was
excluded, making the diagnosis of type 1 HAE. The patient
presented several times to the emergency department with
severe abdominal pain, diffuse abdominal tenderness with
guarding. However, laboratory and imagiologic studies had
no alterations. A subcutaneous injection of icatibant was administered with resolution of symptoms. HAE is a rare and
potentially fatal disease, mainly during acute attacks. An early diagnosis and a proper treatment are fundamental.
