Juan Rosai Biography, Age, Height, Wife, Net Worth and Family

Rosai developed Parkinson’s disease in his late 60s. It was well-controlled for many years, but he died from complications of the condition in July 2020 at the age of 79.

Rosai was an author of more than 400 scientific peer-reviewed papers on topics in pathology, including the seminal descriptions of entities such as sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease), desmoplastic small round cell tumor, spindle-cell epithelial tumor with thymus-like differentiation of the thyroid, and sclerosing angiomatoid nodular transformation of the spleen. He was Editor-in-Chief of the International Journal of Surgical Pathology until 2014 and served as a member of the editorial boards of several other pathology journals. Rosai was also Editor-in-Chief of the 3rd Series of the Atlas of Tumor Pathology of the Armed Forces Institute of Pathology (AFIP), and author of AFIP fascicles on Tumors of the Thymus and Tumors of the Thyroid Gland, and a book on the history of American surgical pathology called Guiding the Surgeon’s Hand. He has also edited or co-edited 13 other books.

During his career, Juan Rosai accumulated a comprehensive collection of slide seminars including histopathology slides of interesting and educational pathological cases with the comments by connoted pathologists. In 2010 Rosai donated his entire seminars collection as an open and free educational resource. Thanks to a collaborative effort between Rosai, the United States and Canadian Academy of Pathology (USCAP) and Aperio ePathology the slide seminars are available as digital pathology files which can be freely accessed by pathologists across the world. The collection consists of 18,439 cases originally presented at 1,495 pathology seminars, and comprises digital images of the original histopathological slides, clinical history, and diagnostic summaries, along with commentaries by Rosai and other experts.

Juan Rosai maintained ties to Italy, his home country, throughout his life. In 1982–1983 he spent a sabbatical year at the University of Florence and the University of Bologna. In 2000 Rosai moved permanently back to Italy as Chairman of the Department of Anatomic Pathology at the Istituto Nazionale dei Tumori (National Cancer Institute) in Milan, Italy. Later, in 2005, he created the Center for Oncologic Pathology Consultations, located at the Centro Diagnostico Italiano in Milan, where he continued his consultation and educational activities focusing on oncological surgical pathology.

Rosai completed his residency and fellowship in anatomic pathology at Washington University School of Medicine and Barnes Hospital under Lauren Ackerman’s mentoring. Subsequently, he remained on the faculty of Washington University until 1974 when, at the age of 34, Rosai was appointed Professor & Director of Anatomic Pathology at the University of Minnesota. He left there in 1985 for an identical position at Yale University School of Medicine in New Haven, Connecticut, where he stayed until 1991. From 1991 to 1999, Rosai was the James Ewing Alumni Professor and Chairman of Pathology at Memorial Sloan-Kettering Cancer Center in New York City.

Perhaps the most famous publication by Juan Rosai is his textbook called Rosai and Ackerman’s Surgical Pathology. This classic surgical pathology textbook was first published in 1953 by Rosai’s mentor, Lauren Ackerman, as a pathology book focused on the differential diagnosis and morphological features with clinical significance. Over the years, the new editions of Ackerman’s book were continued by Rosai until its tenth edition published in 2011. Rosai’s textbook is well known among pathologists due to its clear and didactic style, including illustrations as examples of key diagnostic features. Rosai’s pathology textbook has been influential in the education in surgical pathology across the world and it has been translated to several languages including Spanish, Chinese, Italian and Croatian besides its original edition in English language. Rosai and Ackerman’s Surgical Pathology textbook is currently continued in its 11th edition (2018) by a team of experts in the field of pathology.
