Dr. Schiffman received his B.S. degree with High Honors in biology from Hobart College in 1976. He then moved to Chicago where he studied biochemistry at the University of Illinois, Chicago Circle. He attended Rush Medical College where he received his M.D. degree in 1982 and was elected to the Alpha Omega Alpha Medical Honor Society. He completed his Internal Medicine internship and residency at the University of California, Irvine.
Dr. Balentine received his undergraduate degree from McDaniel College in Westminster, Maryland. He attended medical school at the Philadelphia College of Osteopathic Medicine graduating in1983. He completed his internship at St. Joseph's Hospital in Philadelphia and his Emergency Medicine residency at Lincoln Medical and Mental Health Center in the Bronx, where he served as chief resident.
Neurofibroma (a noncancerous tumor made up of nerve fibers)
Blastoma (a tumor composed mainly of immature, undifferentiated cells)
Sarcoma (a tumor made up of connective tissue [usually cancerous])
Inflammatory (infectious): Granuloma (small, granular inflammatory lesions) These usually involve an exposure to an infectious agent. This agent is difficult for the body to completely remove so the immune system attacks trying to wall it off. Because the immune cells are coming from all angles, the resultant biproduct is a rounded nodular density, an
solitary pulmonary nodule.
Sarcoidosis (a disease characterized by granular lesions of unknown cause that involves various organs of the body,
and now believed to be in some way related to noninfectious inflammation
against proteins from bacteria in the tuberculosis family)
Sequestration (a piece of lung tissue that has become separated from the surrounding healthy tissue
often an embryonic developmental abnormality)
Lung cyst (an abnormal sac that contains gas, fluid, or a semisolid material, with a membranous lining,
a malformation that occurs during embryologic development)
Pulmonary infarct (death of cells or of a portion of lung, resulting from a sudden insufficiency of arterial or venous blood supply
to a small portion of the lung)
Round atelectasis (decreased or absent air in a part of the lung)
Progressive massive fibrosis (formation of fibrous tissue as a reactive process, as opposed to formation of fibrous tissue as a normal constituent of an organ or tissue)
Occasionally, a shadow seen on X-ray from an overlying object lying on the back or the chest may be mistaken for an
solitary pulmonary nodule. Similarly, when several objects, such as blood vessels, lymph nodes, and or ribs overlap, the result can seem like a nodule or mass on chest
X-ray when one does not really exist.
