Dr. Peter Sadow is an ENT Pathologist at Mass. Eye and Ear and the Director of Head and Neck Pathology at Massachusetts General Hospital, where he directs the Anatomic Pathology residency program and is also a subspecialist in Genitourinary Pathology and a consultant in Endocrine Pathology. With a desire to advance our knowledge of human disease, Dr. Sadow pursued a combined M.D./Ph.D. program at the University of Chicago. There, his doctoral thesis utilized transgenic mouse models with altered thyroid hormone response genes in order to understand the effects of thyroid hormone on human physiology. This desire to understand the pathophysiology of endocrine dysfunction led Dr. Sadow to subsequently pursue clinical training in anatomic pathology at Brigham and Women's Hospital, followed by subspecialty training in endocrine, genitourinary, and head and neck pathology. 

His clinical and research interests have continued in endocrine pathology, studying the mechanisms of endocrine carcinogenesis through translational studies involving the proteomics and genomics of endocrine neoplasia, primarily of the thyroid and adrenal glands. His Mass. Eye and Ear research has also involved pediatric laryngeal pathology and lesions of the sinonasal tract.

In addition to his clinical and research interests, Dr. Sadow has a prominent teaching roles at Mass General, Harvard Medical School, and in continuing medical education courses.
