This research addresses the challenge of identifying two common fungal infections (cryptococcosis and histoplasmosis) when examining tissue samples under a microscope. The study found that these infections often look similar and can be confusing for pathologists. The researchers discovered that looking for specific fungal features, particularly ‘dented-looking’ yeasts, can help differentiate cryptococcosis from histoplasmosis. When standard laboratory tests on fresh tissue aren’t available, using molecular testing (genetic analysis) on preserved tissue samples can successfully identify the fungus in about 75% of cases.
