Abstract

IN the past few years we have seen an increasing number of goiters which are classified as Hashimoto's type of chronic thyroiditis. We want to bring this to your attention, along with several other observations we have made in the 28 cases of the disease seen from 1935 to the present time. All but 2 of these cases were encountered since January, 1943.

In 1912 Hashimoto (1) described “struma lymphomatosa,” which differed from other forms of chronic thyroiditis and especially from Riedel's (2, 3, 4) “eisenharte struma.” Since that time there has been considerable controversy as to whether they actually are different processes.

In 1922 Ewing (5) studied 4 cases and concluded that Hashimoto had described the early, and Riedel the late stages of the same process. Others who take this same view include Boyden, Coller and Brugher (6), Perman and Wahlgren (7), Williamson and Pearse (8), Heyd (9), Eisen (10), Womach (11), Reist (12), and Shaw and Smith (13). In 1931 Graham and McCullagh (14) gave impressive support to the belief that these are two separate types of thyroiditis. McClintock (15), and Scarello (16), have shown that the tissue of the thyroid did not change from the Hashimoto type toward the Riedel type, but remained the same, judging from biopsy specimens taken two and thirteen years later respectively. Lee (17), Joll (18), Heineke (19), Moore and Lloyd (20), Lee and McGrath (21), Poer, Davison and Bishop (22), McSwain and Moore (23), and Decourcy (24), join the ranks of the separate entity followers. DeCourcy (25), furthermore, suggests that it is possible to have both processes in the same gland simultaneously.
