Gastrointestinal Flags

San Francisco - One of the basic tenets of medical dermatology is that the skin serves as a window into the internal parts of the body and internal diseases. Visual examination of the skin can reveal signs of systemic disease, including gastrointestinal disease such as GI polyposis syndromes, inflammatory bowel disease, GI malignancy, hepatobiliary disease, nutritional deficiencies, and other disorders, according to dermatologist Amit G. Pandya, M.D., University of Texas Southwestern Medical Center, Dallas.
