The story of poorly differentiated thyroid carcinoma

Thirty years ago Rosai, reinterpreting Langhans’ “proliferating goiter”, adopted the term “Poorly differentiated carcinoma” for a specific thyroid tumor with insular features. This tumor type is only one of those approached by dr. Rosai in the thyroid field (a Pubmed search as of August 31 2015 on “Rosai & thyroid” disclosed 73 articles), but seems the most innovative and representative of his heavy contribution to thyroid tumor classification. The diagnostic problems associated to PDTC recognition date back a long time, with a still ongoing debate on the nature of PDTC, its morphological diagnostic features, its clinical significance and its optimal therapeutic approach.
