Nocardia farcinica is an aerobic gram-positive bacterium that is pathogenic to humans. It usually causes local and adjacent tissues’ diseases at the entry of infection (most commonly occur in the lungs, skin, or central nervous system), which can also spread to other organs through the bloodstream such as joints, kidneys, and liver. However, these infections are often seen as opportunistic that occur in immunocompromised patients. Here, we report for the first time two immunocompetent patients lacking evidence of local infections, with multiple lymph node enlargements and fever as main clinical manifestations, finally diagnosed as nocardiosis by Metagenomic Next-Generation Sequencing testing (mNGS) from formalin-fixed and paraffin-embedded (FFPE) lymph node tissue, after all the other standard tests were negative. Both patients recovered after receiving anti-nocardia therapies. These two cases indicates that in healthy population, there may be more potential nocardia infections than we expected. Multiple lymph node enlargements and fever suggest a possibility of nocardiosis, especially in patients with fever of unknown origin (FUO). mNGS detection from FFPE lymph node tissue is an accurate, reliable and traceable method for diagnosis of nocardiosis. |
