[Schilddrüse und polyendokrinopathien]

The thyroid gland can be affected in the course of several polyendocrinopathy syndromes either by impairment of physiological function or thyroid carcinoma. The various syndromes -- polyglandular autoimmune syndrome, autoimmune hypophysitis, multiple pituitary hormone deficiency, multiple endocrine neoplasia, and Carney complex -- are discussed. Therapy of thyroid dysfunction is identical whether it is part of a specific syndrome or not. Genetic testing for mutations, however, has had an enormous impact on screening procedures and therapeutic consequences.
