Comparative immunological and histopathological study in fifty cases of mucosal/nonmucosal lichen planus.

Lichen planus is a common disorder and 40-50% of LP patients also reveal mucosal lesions. It is well known that mucosal LP lesions take very long to heal in comparison to cutaneous lesions. Rarely erosive mucosal LP can turn malignant. Both CMI and humoral immunity may play role in aetiopathogenesis of LP. Present study was conducted to study and compare CMI, Humoral Immunity, histopathology in mucosal and nonmucosal LP.
