Edward C. Rosenow III, M.D.
Dr. Edward Rosenow III sees a natural link between the Information Age and health care as a way to promote better health. Dr. Rosenow, a Columbus, Ohio, native, is board certified in internal medicine and pulmonary disease and worked in the Division of Pulmonary and Critical Care Medicine, Mayo Clinic, Rochester, Minn. He retired from clinical practice in 1996 after 30 years' service at Mayo Clinic.
"It has always been my feeling that the better informed the patient is about his or her body and its functions, the better the patient-physician partnership," he says. "The informed patient is in turn more compliant with the physician's recommendations and better able to make intelligent decisions about health care needs."
Dr. Rosenow is a former Arthur M. and Gladys D. Gray Professor of Medicine and former chair of the Division of Pulmonary and Critical Care Medicine at Mayo Clinic. He was also president of the American College of Chest Physicians, consultant to NASA on the Space Station Freedom project, president of the Mayo Clinic staff, a regent with the American College of Chest Physicians and program director of the internal medicine residency program at Mayo Clinic.
During his distinguished career, Dr. Rosenow was a five-time Teacher of the Year in internal medicine and inducted into the Mayo Fellows Hall of Fame of Outstanding Teachers.
In 1994, he won the Distinguished Mayo Clinician Award from Mayo Clinic staff and in 1995 was honored with the Ralph O. Claypoole Sr. Memorial Award for Lifetime Dedication to Patient Care by the American College of Physicians. He was named to a mastership by the American College of Physicians in 1998 and that year also won the Mayo Foundation Distinguished Alumnus Award. He is also a Master Fellow in the American College of Chest Physicians. In 2008, a professorship was established in his name — the Edward C. Rosenow III, M.D., Mayo Professorship in the Art of Medicine.
Dr. Rosenow has contributed to 156 publications, including 48 book chapters and one co-authored book.

Question
Granuloma: What is it?
My mother-in-law recently had a chest X-ray and was told she has granuloma in her lungs. What does that mean?
Answer
from Edward C. Rosenow III, M.D.
A granuloma is a small area of inflammation in tissue due to injury, such as from an infection. Granulomas most often occur in the lungs but can occur in other parts of the body as well. They typically cause no signs or symptoms and are found incidentally on a chest X-ray done for some other reason. Although granulomas are noncancerous (benign), they may resemble cancer on an X-ray.
The most common cause of granuloma is histoplasmosis, a fungal infection that primarily affects the lungs. Most people with pulmonary histoplasmosis never suspect that they have the disease. Granulomas due to histoplasmosis are usually visible on X-rays because they become calcified and have the same density as bone.
A doctor may make a diagnosis of granuloma by a chest X-ray or computerized tomography (CT) scan. The images of affected tissue usually show scarring and calcification characteristic of a granuloma. Most granulomas don't require treatment.
