ABSTRACT

Lichen planus is a chronic mucocutaneous disease, inflammatory condition, autoimmune nature and unknown etiology, in which an aggression is produced by the T lymphocytes against the basal cells of the epithelium of the buccal mucosa. Clinically, it could present itself as a plaque similar to leukoplakia, with multifocal distribution. It also may stands as reticular lesions or white lines, whose appearance is comparable to a network (Wickham’s striae). Moreover, lichen planus may be accompanied by subjective symptoms; the most common are heat and burning sensation of the mucosa. The lesions may affect skin and buccal surface (40%), exclusively to the skin surface (35%) or only to the mucosa (25%). The diagnosis can often be made based on clinical findings, but for a definitive diagnosis is always necessary an incisional biopsy and direct immunofluorescence is always required. A clinical case of a female patient presenting a white macula erythematous areas with irregular borders with six month history of symptomatic is presented. She underwent incisional biopsy with histopathological diagnosis to support lichen planus atrophic bullous variant.
