The term RDD was first introduced into scientific literature in 1969 when Juan Rosai
and Ronald Dorfman described four cases of a rare, idiopathic, non-neoplastic lymphoproliferative disorder.

, MD, a world-renowned expert and consultant in surgical pathology, has established relationships with a number of pathologists who often refer cases and ship glass slides to him in Milan, Italy.
In the same year, just a few months earlier, Juan Rosai
(2) argued in favor of the continuing importance of morphology in daily diagnostic practice.
In 1989, a "WHO [World Health Organization] committee for the histologic classification of tumours of the thymus" was organized by Dr Juan Rosai
. Subsequently, pathologists from 8 countries debated during 1 decade whether a histologic subclassification of thymomas is possible and useful.
This falls around the range quoted by Juan Rosai

Dr Scully and Juan Rosai
, MD, had independently recognized that operative procedures could elicit an exuberant spindle cell proliferation likely to be misdiagnosed as sarcoma, and when they realized they had a shared experience, they reported their cases as a group.
Originally described by Juan Rosai
and Ronald Dorfman in 1969, (1) RDD was observed as a triad of massive cervical lymphadenopathy, expanded lymph node sinuses, and characteristic emperipolesis within histiocytes.
In 1991, Juan Rosai
, MD, joined the faculty as chairman of the Department of Pathology.
