Department and Faculty

The Pulmonary Pathology Fellowship staff of teaching consultants

The Department of Laboratory Medicine and Pathology at Mayo Clinic is one of the largest clinical laboratories in the world. A highly skilled team of medical professionals including physicians, scientists, medical technologists, medical technicians, lab assistants, biologists, chemists, microbiologists, geneticists, and other specialists work collaboratively. The department receives specimens for testing from Mayo Clinic and Mayo Clinic Health System and is a reference laboratory for other clinics and hospitals, both nationally and internationally.

The Division of Anatomic Pathology has 60 pathologists, with specialty expertise covering the entire field of surgical pathology. The division is organized around working groups dedicated to specific organ systems, but all members contribute service to general areas as well, such as frozen section lab, autopsy, and cytology.

The division is supported by a full-service histology and immunohistochemistry laboratory, an active electron microscopy section, and a growing molecular pathology laboratory. The hospital surgical pathology practice is unique in its heavy reliance on rapid frozen section diagnosis, providing trainees with a valuable opportunity for immediate correlation of gross and microscopic pathology.

From the director

Anja Roden, M.D.Welcome to our Pulmonary Pathology Fellowship website! We hope this website will be informative, but please feel free to email me with any questions.

We have been training fellows as part of our Pulmonary Pathology Fellowship since 1996. We were accredited by the Accreditation Council for Graduate Medical Education in 2005. Since then, we have been continuously accredited without any citations.

The mission of our fellowship is to train pathologists to become experts in understanding and diagnosing routine, complex, and esoteric pathologic specimens from the lung, pleura, and mediastinum; become consultants to other pathologists on these cases; and advance the science of pulmonary pathology through clinical and transitional research.

While at Mayo Clinic, you will be exposed to a large clinical practice, many research and teaching opportunities, and a large faculty dedicated to your educational success. We have trained many successful pulmonary pathologists and wish to provide the necessary experience for your specific career goals.
