Dynamic concept of oral lichen planus. The diagnosis easy at early stages may become difficult in ancient lichen planus. Lichen planus is a chronic inflammatory dermatosis of the skin, skin appendages and mucous membranes, which frequently affects the oral mucosa.

Analysis of the expression of heat-shock protein 27 in patients with oral lichen planus.

Objective: Heat-shock protein 27 (hsp27) has been implicated in several biological events. In this experimental study, we aimed at analysing, for the first time, the expression of hsp27 in the diverse stages of oral lichen planus (OLP) lesions.

Materials And Methods: Thirty-six biopsy specimens of patients with OLP and 10 of healthy patients were selected.

New perspectives on the dynamic behaviour of oral lichen planus.

Lichen planus, a chronic inflammatory disease that affects the skin and mucous membranes, is one of the most frequent dermatological disorders of the oral cavity. The prevalence of oral lichen planus ranges from 0.2% to 4%.
