 Abstract


A 70-year-old man presenting with a chief complaint of tongue swelling had been diagnosed with prostate cancer 1 year earlier. He had been on an oral angiotensin-converting enzyme inhibitor (ACE) inhibitor for hypertension for 20 years. Two months before the fi rst of 4 episodes of tongue swelling within a period of 40 days, he had been prescribed oral estramustine phosphate (EMP) for the prostate cancer. He was admitted to our hospital for the evaluation after massive swelling of the tongue and epiglottis which necessitated tracheotomy. Food allergies, allergic reactions to environmental factors, and hereditary angioneurotic edema were excluded. Massive swelling of the tongue and epiglottis disappeared completely after EMP was discontinued. We concluded that angioedema was induced by EMP used concurrently with the ACE inhibitor.

Key Words: Estramustine phosphate. Angiotensin-converting enzyme inhibitor. Angioedema. Tracheotomy. Prostate cancer.
