The nucleolus was positive for fluorescent staining, suggesting the presence of anti-nucleolon ribonucleic acid antibodies. SSc or other rheumatism that overlaps with SSc may be positive. Antinuclear antibody (ANA), also known as anti-nucleic acid antigen antibody, is a group of various components of eukaryotic cells, such as deoxyribonucleoprotein (DNP), DNA, extractable nuclear antigen (ENA) and RNA. The general term for autoantibodies of antigens can react with the nucleus of all animals, mainly in serum, but also in pleural fluid, joint synovial fluid and urine.
