Atrophic, autoimmune thyroiditis in infancy. A case report.

ABSTRACT

Autoimmune thyroiditis in infancy is a very rare condition. Only 1 case has been reported previously. In the present patient an acquired primary hypothyroidism with high titers of thyroid microsomal antibodies was diagnosed at the age of 7 months. The patient died at 9 months of age in a sepsis-like condition. Autopsy revealed an atrophic thyroiditis. The more severe and complex clinical picture of autoimmune thyroiditis in infancy compared to that later in childhood is discussed.
