• A total of 164 articles were included, representing 985 patients.

• The most common clinical signs were flat-topped papules (51%), with a linear variant present in 9%.

• Oral involvement was present in 22% of the cases.

• Topical corticosteroids were the most commonly used treatment, followed by systemic corticosteroids.

• The average treatment time was 124.4 days.

• LPP patients had a shorter disease duration before diagnosis and were more likely to fail earlier treatments.
