What’s New in Inflammatory and Fibrotic Lung Disease?

 

Organizing pneumonia is not a new diagnosis but histologic variation can make recognition challenging. The hyalinized variant and its differential will be emphasized. In addition, granulomatous lung disease includes a few new entities, less familiar to general pathologists, but even rudimentary knowledge of them can help narrow the differential diagnosis in certain circumstances e.g. lung disease in common variable immunodeficiency, and primary biliary cholangitis. Finally, the lecture will focus on lung toxicity in patients on immune check point inhibitors.

Originally presented on February 11, 2019, in Park City, Utah.

Lecture Presenter

Henry D. Tazelaar, MD

Henry D. Tazelaar, MD

Professor of Laboratory Medicine and Pathology
Consultant, Department of Laboratory Medicine and Pathology
Mayo Clinic in Arizona

Dr. Henry Tazelaar is Chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic in Arizona, and he is a Consultant in the Division of Anatomic Pathology in Arizona. Dr. Tazelaar also serves as Chair of the Laboratory Medicine and Pathology Specialty Council. He joined the staff of Mayo Clinic in 1988 and holds the academic rank of Professor of Laboratory Medicine and Pathology.

Dr. Tazelaar earned his Bachelor of Arts degree at Calvin College in Grand Rapids, Michigan, and his M.D. at Rush Medical College in Chicago. He completed both an internship and residency in pathology at Stanford University Medical Center, followed by a National Institutes of Health postdoctoral fellowship in the pathology of heart-lung transplantation in the laboratory of Dr. Margaret Billingham at Stanford University Medical Center, where he subsequently completed a fellowship in surgical pathology.

Dr. Tazelaar’s work has focused on refining criteria used to diagnose the rejection of transplanted hearts and lungs. He is also active in identifying new pulmonary diseases and better understanding how systemic diseases affect the lungs and pleura. His observations have led to the identification of several new or unusual pulmonary diseases.

Clinically, Dr. Tazelaar is a surgical pathologist, a role that includes a large thoracic consultation practice offering second opinions on biopsy and cytology specimens. He is also an active educator, providing mentorship to a multitude of residents and fellows. In addition, he has taught in the Cytotechnology Program of the Mayo Clinic School of Health Sciences and Mayo Clinic School of Medicine.

Dr. Tazelaar is a fellow of the American College of Chest Physicians and College of American Pathologists, where he is a member of the Pulmonary and Mediastinum Tumors Cancer Protocol Review Panel. He is active in many other professional organizations, serving on numerous committees and in leadership roles, including a tenure as president of the Pulmonary Pathology Society. He was also a member of the International Society for Heart and Lung Transplantation groups that standardize reporting of heart and lung rejection. Dr. Tazelaar is currently Treasurer of the International Academy of Pathology and Chair of the Finance Committee of the United States and Canadian Academy of Pathology.

Objectives

After this presentation, participants will be able to:

  • Recognize the hyalinizing form of organizing pneumonia and state its differential diagnosis
  • List diseases in which small granulomas may be identified in lung tissue, including connective tissue disease, hypersensitivity pneumonitis, immunodeficiency states and primary biliary cholangitis
  • Identify check point inhibitor lung toxicity
