M169 acquired angioedema in the setting of multiple autoimmune disorders

Acquired angioedema (AAE) is a rare disorder characterized by recurrent episodes of swelling without hives and C1 esterase inhibitor deficiency. Although clinically it presents similarly to hereditary angioedema, AAE generally develops in older patients and is associated with underlying disease, most notably lymphoproliferative disorders and autoimmune conditions.
