**8.4 Undifferentiated connective tissue disease (UCTD)**

NFC can help in the establishing the presence of a connective tissue disease in a patient with equivocal findings. Scleroderma pattern is observed in 9/65 (13.8%) of patients with UCTD in one study [37]. Approximately a quarter of the patients with UCTD may transform into SSc on follow-up [38]. Hence capillaroscopic examination could be of value in identifying the patients of UCTD who could progress to SSc on follow-up.
