    TLDR Pigmented rings with central clearing help diagnose melasma more accurately.
    The study introduces a novel dermoscopic feature called pigmented rings with central clearing (PRCC) to aid in the diagnosis of melasma, a challenging pigmentary disorder affecting the face. This feature helps distinguish melasma from other similar conditions, addressing the diagnostic difficulties often encountered with this disorder. The study highlights the potential of PRCC as a valuable tool in improving the accuracy of melasma diagnosis.
