title: Acquired angioedema.
abstract: An unusual case of angioedema is presented. The initial presentation occurred at 84 years-of-age without a family history of this condition. Further investigation revealed an underlying lymphoproliferative disorder which was associated with an acquired deficiency of the complement component C1 esterase inhibitor. It is important to distinguish this condition from the hereditary form.
