Abstract

Bhutani et al. originally described a pigmented variety of lichen planus (LP) from India in 1974, and created the label LP pigmentosus (LPP) to better describe it. LPP is one of several variations of the LP gene. This skin lesion has also been reported in the Middle East, Latin America, Korea, and Japan, and is more common in those with darker skin. The most common differential diagnosis for LPP is erythema dyschromicum perstans (EDP). Fixed drug eruption, macular amyloidosis, urticaria pigmentosa, tar melanosis, frictional melanosis, berloque dermatitis, pigmented beautifying dermatitis (Reihl's melanosis), and pigmented beautifying dermatitis (Reihl's melanosis) are some of the other differences. Cutaneous LP usually clears up on its own after 1 to 2 years, thus care focuses on lowering pruritus and speeding up the healing process. First-line management for limited LP is superpotent interesting steroids (clobetasol 0.05%) twice daily for 2 to 4 weeks. This study aims to: 1- Recognize the causes and risk factors for lichen planus 2- Correct diagnosis of lichen planus 3- Provide effective treatment for lichen planus
