title: A pathomorphic study of chronic thyroiditis.
abstract: The authors studied the pathomorphy of 364 cases of chronic thyroiditis including Hashimoto's thyroiditis (67 cases), Hashimoto's thyroiditis associated with thyroid cancer (21 cases), De Quervain's thyroiditis (10 cases), tuberculous thyroiditis (6 cases), and 260 cases of focal thyroiditis without manifest clinical symptoms appearing in 10% of euthyroid polynodular goitres. A personal classification of chronic thyroiditis is presented. The high incidence (24%) of association between thyroid cancer and the fibrous type of Hashimoto's thyroiditis is emphasized. A morphometric investigation showed the highest sclerosis percentage in De Quervalin's thyroiditis.
