[Oral lichen planus and chronic hepatopathy. Clinico-statistical study].

Recent researches on the aetiopathogenesis of lichen planus have revealed a significant physiopathological and clinical association of this disease with the chronic hepatopathies. A clinico-statistical investigation has been carried out for the purpose of ascertaining the real importance of oral LP in the economy of this association. The results substantially demonstrated that oral LP, particularly the erosive variety, rather than cutaneous or cutaneous-mucosa clinical forms, occupies a central role in relation to association with the chronic hepatopathies (an important factor for diagnosis and predictive purposes). It has also been found that the erosive variety presents a significantly higher frequency in forms of LP with an exclusively oral involvement. Hence the need to propose an interdisciplinary type clinico-diagnostic approach to LP patients, particularly those with erosive type oral LP.
