This study examines rare but serious fungal infections in patients with chronic granulomatous disease, a genetic immune disorder. Researchers analyzed 122 cases of non-Aspergillus fungal infections from French hospitals and published literature, finding that these infections often occur despite preventive antifungal medications and are challenging to diagnose. The infections were found in the lungs most commonly but could spread to bones, brain, and other organs, with treatments including antifungal drugs, surgery, and in some cases bone marrow transplants.
