Distribution of Lichen Planus at Extra Oral Site in Oral Lichen Planus Patients

mucosa are the most frequently involved areas. Other mucous membranes (including the genital, esophagus, and conjunctiva) and skin appendages (e. g. scalp, hair and nails) can also be affected. Oral lichen planus (OLP) is a chronic inflammatory mucous disease. WHO consider OLP as a precancerous condition at 2005, but the premalignant potential of OLP is still debatable. Malignant transformation has been estimated to occur in 0.5 -2.9 % of the OLP patients. Materials and Methods The study comprised from 60 OLP patients, the patients was diagnosed by clinical examination, Subjects were excluded if they were edentulous, pregnant, were took medications, or were receiving operative treatment, with no evidence of severe chronic periodontitis or autoimmune diseases such as SLE and RA. Results The highest number of cases, 20 cases (33.3 %) from 30-39 years, The lowest number of cases appear at so young and old age patients as four cases (6.66 %). The highest frequency at sex distribution is female, it form (73.3 %). The highest number of oral lichen planus types at reticular form, it form (86.6 %). The highest number of distribution LP at other site of body in OLP patients at cutaneous part all over the body, it form (33.3 %). The lowest frequency at nail and this consider as a rare case, it form (3.3 %). Conclusion Data was shown that LP at other site of body can associated with OLP in (86.6 %), Nail lichen planus (NLP) appear as one case even it consider as a rare case.
