Chronic granulomatous disease

Chronic granulomatous disease (CGD) is a group of rare, inherited disorders of the immune system that are caused by defects in the immune system cells called phagocytes. These defects leave patients vulnerable to severe recurrent bacterial and fungal infections and chronic inflammatory conditions such as gingivitis (swollen inflamed gums), enlarged lymph glands, or tumor-like masses called granulomas. While not malignant, granulomas can cause serious problems by obstructing passage of food through the esophagus, stomach, and intestines as well as blocking urine flow from the kidneys and bladder.
