Significant positive correlation between body surface area involvement and disease duration was observed (<jats:italic>r<\/jats:italic>\u00a0=\u00a00.72). Personal history of atopy and accompanying autoimmune diseases were observed in 49 (14.24%) and 45 (13.08%) patients, respectively. Observed morphological patterns of LPP included diffuse (<jats:italic>n<\/jats:italic>\u00a0=\u00a0193, 56.1%); reticular (<jats:italic>n<\/jats:italic>\u00a0=\u00a045, 13.1%); blotchy (<jats:italic>n<\/jats:italic>\u00a0=\u00a041, 11.9%); and follicular (<jats:italic>n<\/jats:italic>\u00a0=\u00a028, 8.1%).
