Intraoperative Onychoscopy and Histopathological correlation of Red Lunula in Nail lichen planus: A case series.

: The lunula is the white half-moon-shaped area located at the base of fingernails and toenails. It is the only visible part of nail matrix. Red lunula can present as a complete form (whole lunula is red), incomplete form (only proximal lunula is red) or as mottled form. Red lunula has been associated with a number of dermatologic and systemic conditions. It is one of the less common manifestations of nail lichen planus. However, the pathogenesis of the red lunula is not yet clear. We present a series of 6 patients with nail lichen planus presenting as red lunula with an attempt to understand the pathogenesis with the help of intra-operative onychoscopy and histopathology.
