Thyroid disorders were detected in 3.7% of our 269 cases of sarcoidosis histologically confirmed. This is close to the rate in the literature. As a probability of this complication that some of closely allied autoimmune disorder may relate both disease, except by chance. In 2 of our cases, these diseases appeared alternately as follows. A 49 years old woman suffered from granular-hard struma with hypothyroid from 4 years ago when sarcoidosis had completely healed. On the other side, a 55 years old woman had the apparent struma for about 16 years from her 6 years of age and gradually disappeared after the signs of sarcoidosis became apparent. She also had a Basedow's patient in her family.
