A Case Report on Autoimmune Thyroid Disease (ATD) Associated with Chronic Angioedema

Angioedema may be a rare condition that manifests itself by abrupt localized edema caused by the fluid outflow from blood vessels into surrounding skin and tissue. This case report presents a 54-year old male patient with chronic angioedema (lip) for one year without urticaria. Six months ago, he approached the local clinic and used regular antihistamines by the physician advice. Still, there was no improvement in patient condition. Then he came to the outpatient department of internal medicine of our hospital. Therefore, we have done a series of investigations, in then he diagnosed with Hypothyroidism (TSH 8.05UIu/ml). Then he has prescribed levothyroxine 25mcg. After one month's review, he examined for Anti-thyroid peroxidase antibodies (Anti-TPO). In that examination, those were positive or elevated (mild). According to our research, this may probably be the first autoimmune thyroid disease associated with chronic angioedema without urticaria or hives.
