Lichen planus is a chronic, immunologic, mucocutaneous disease with a wide range of clinical manifestations. The aim of this retrospective study was to evaluate the most common forms of oral lichen planus (OLP) and its symptoms and to describe treatment responses in patients during 10-year period.
The study was conduced on 163 OLP patients who came in the Department of Oral medicine and Periodontology between 1997 and September 2007. Each case was classified into one of four clinical subtypes: reticular, atrophic, erosive-ulcerative, bullous.
There was no significant difference in patients age. Women were found to be significantly more likely to have OLP (p < 0.001). Corticosteroids were effective in reducing symptoms, erythema and healing ulcers. Improvement was shown over a long term in 61.35% patients. Over the long term 38.65% patients maintained the same type of OLP or it became a more severe type. Two patients (1.22%) developed oral carcinoma during the follow-up period.
The response of patients with erosive OLP to a short course of systemic corticosteroids often was quite remarkable. However, symptoms and signs tended to recur after this treatment. Periodic examinations, patient education, medical treatment, monitoring of side-effects as well as follow-up biopsies are necessary for management of OLP patients.

    • "The most serious complication of OLP is the development of oral cancer, which occurred in 4 (0.7%) of our patients. The rate of malignant transformation of OLP is reported to be 0.07% to 5.8% (2,4,6-9,11,20-22), which places our patient population among ones with lower malignant transformation rates. Malignant transformation is more common among women (5,12,15), even though there are studies that report higher incidence of malignant transformation among men (4). "

    ABSTRACT: Objectives: To investigate the epidemiological and clinical characteristics of oral lichen planus (OLP) in a group of Croatian patients seen between 2006 and 2012. Study Design: A group of 563 patients with a diagnosis of OLP was retrospectively reviewed in our clinic. Data regarding age, gender, medical history, drugs, smoking, alcohol, chief complaint, clinical type, localization, histology, treatment and malignant transformation were registered. Results: Of the 563 patients, 414 were females and 149 were males. The average age at the diagnosis was 58 (range 11-94). The most common site was buccal mucosa (82.4%). Most of our patients did not smoke (72.5%) or consume alcohol (69.6%). Patients reported oral soreness (43.3%), mucosal roughness (7%), xerostomia (3%), gingival bleeding (2%) and altered taste (0.5%) as the chief complaint, while almost half of them were asymptomatic (44.2%). The most common types of OLP were reticular (64.8%) and erosive (22.9%). Plaque-like (5.7%) atrophic/erythemtous (4.3%) and bullous (2.3%) type were also observed. Malignant transformation rate of 0.7% was recorded. Conclusions: OLP mostly affects non-smoking middle-aged women. Buccal mucosa is the most commonly affected site. In almost half of the cases patients are asymptomatic. In spite of the small risk for malignant transformation all patients should be regularly monitored. Key words:Oral lichen planus, malignant transformation, epidemiology, retrospective study.

    ABSTRACT: Background: Determining the potential for malignant transformation of oral lichen planus (OLP) is complicated by difficulties in diagnosis, differentiation from oral lichenoid lesions (OLLs) and the phenomenon of premalignant lesions' exhibiting lichenoid characteristics. The authors of this systematic review evaluated evidence regarding malignant transformation of OLP and characterized transformation prevalence, clinical characteristics of OLP lesions developing into squamous cell carcinoma (SCC) and time to transformation. Types of studies reviewed: The authors searched PubMed, Embase and Thomson Reuters Web of Science in a systematic approach. They evaluated observational English-language studies involving human participants published in peer-reviewed journals. Inclusion required patients to have the diagnosis of OLP or OLL as confirmed with biopsy results on initial enrollment. They excluded all patients who had dysplasia on initial biopsy of OLP or OLL lesions. Results: Sixteen studies were eligible. Among 7,806 patients with OLP, 85 developed SCC. Among 125 patients with OLL, four developed SCC. The rate of transformation in individual studies ranged from 0 to 3.5 percent. The overall rate of transformation was 1.09 percent for OLP; in the solitary study in which investigators evaluated OLL, the rate of transformation was 3.2 percent. Patients' average age at onset of SCC was 60.8 years. The authors noted a slight predominance of female patients among those who experienced malignant transformation. The most common subsite of malignant transformation was the tongue. The average time from diagnosis of OLP or OLL to transformation was 51.4 months. Practical implications: A small subset of patients with a diagnosis of OLP eventually developed SCC. The most common demographic characteristics of patients in this subset were similar to the most common demographic characteristics associated with OLP in general (that is, being female, being older and being affected in areas common to this condition). It is prudent for clinicians to pursue continued regular observation and follow-up in patients with these conditions, even in patients who do not fit a traditional high-risk category for oral SCC.
