The aim of this work is to present the clinical and pathological necessary aspects to know better the oral lichen planus and to be able to diagnose it correctly. The diagnosis is obtained first by the clinical aspect of the injuries. It is necessary to realize always biopsy and histopathologyc evaluation to confirm the clinical suspicion and realize differential diagnosis with other entities of clinical similar appearance. The steps that we must follow to realize a diagnosis of certainty are: study of the clinic (anamnesis and clinical exploration), biopsy for histopathological study and analytical blood and determination of the blood pressure, looking for a possible relation with certain systemic processes. It will become a direct inmunofluorescence when it is necessary to differentiate it of similar disease (lupus, pemphigoid or pemphigus). In occasions we will be able to realize a ultraestructural analysis and other diagnostic tests.
