The lichen planus is an autoimmune skin disease muco-cutaneous that affects the oral mucosa (oral lichen planus), and may also affect skin, genital mucosa, scalp and nails. The exact etiology of lichen planus remains unknown. This condition most commonly affects middle-aged women and rarely affects children. Clinically, lesions of oral lichen planus are presented in the form of white streaks (Wickham striae), white papules, white plates, erythematous, bullous or erosive. These lesions are usually bilateral and symmetrical. Diagnosis of oral lichen planus is made only by clinical examination or by clinical examination and histopathology. The treatment of oral lichen planus is realized mainly with topical corticosteroids, however, other drugs have proven effective. Malignant transformation of oral lichen planus and its exact incidence remains controversial. This paper aims to highlight the importance of knowledge of oral and systemic manifestations of lichen planus to contribute to its correct diagnosis, to provide a better prognosis and treatment of patients with this pathology. In addition to the theoretical foundations four clinical cases shall be presented
