  • Chronic granulomatous disease (CGD) is an inherited primary immunodeficiency disease which is one kind of the phagocytic dysfunction. It is accounted for 1 : 200000 live births in the United States. The mechanism of CGD is mutation in any structural molecules of Nicotinamid Adenine Dinucleotide Phosphate (NADPH) oxidase. Therefore, CGD increases the body’s susceptibility to infections caused by bacteria and fungi with granulomas formed at the sites of infection or inflammation. We report 4 cases diagnosed as suspected CGD in patients suffering from persistent pneumonia in the respiratory unit in Vietnam National Children’s Hospital to recommend colleagues not to mis-diagnose CGD...

  • Primary breast diffuse large B-cell lymphoma (DLBCL) is a rare non-Hodgkin’s lymphoma with limited data. We here report a case of primary breast diffuse large B-cell lymphoma mimicking breast cancer. A 52-year old woman had a painless mass in her right breast. Fine needle aspiration cytology and core biopsy were performed which suggested malignant features but could not confirm the specific subtype. Excisional biopsy then was conducted revealing non-Hodgkin lymphoma, which was subsequently confirmed with histopathology and diagnosed as diffuse large B-cell lymphoma (DLBCL). A chest computed tomography scan revealed a 3.5cm sized breast mass with skin thickening and modest ly...
