Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 22-24 Lichen planus is relatively common inflamatory disorder which may have cutaneous and/or mucosal manifestation. The maglinant potential of oral lichen planus is still debatable. Some authors are sceptical about the premaglinant nature of the disease, while other investigators have reporterd that maglinant transformation occur in 1-10% of the cases. The aim of this study is to report a case of erosive oral lichen planus which shows maglinant transformation on histopatologic examination. A man of 39 years old visited the Dental Departement of Kariadi's Hospital with pain symptom of palatum, buccal and gingival mucosa both side for 6 months. On the physical examination shows the white lesions with striae configuration and pain, red erosive area inside on the palatum extends to the buccal mucosa and the gingival. The suspect dignose is erosive lichen planus, but the histopathologic examination shows epidermoid carcinoma. lt is concluded that erosive oral lichen planus has the potential to transform into epidermoid carcinoma.

Oral lichen planus (OLP) is a rather common oral disease, mainly affecting adults, occurring more often in women than in men. The etiopathogenesis is still unclear. The diagnosis may be cumbersome, even in the presence of a biopsy. In addition, there are several lesions that may resemble lichen planus (lichenoid lesions) both clinically and histopathologically. Treatment of OLP can only be symptomatic and usually consists of topical application of corticosteroids. The disease is characterized by remissions and exacerbations and may persist in some patients lifelong. There is an ongoing debate in the literature as whether OLP is a potentially malignant disease. Because of this uncertainty, annual follow-up is advised.

Lichen Planus is a chronic inflammatory disease that effects the skin and mucous membrane of squamous cell origin. Oral Lichen Planus can occur without the skin lesion and there are six types of the oral lesion, erosive, atrophic, bulla, papular, plaque like and retiqular. This disease can be caused by several factor, among them are antihypertensive drugs and emotional stress. In this case report we present a 43 years old female patient who suffered from several types of oral lichen planus that induced by ramipril, an antihypertensive drug, and emotional stress. There were some progressions after the drug was discontinued but the disease was worsening when emotional stress occured. The severity of the disease can be controlled by the use of topical corticosteroid and multivitamins.

Oral lichen planus (OLP) is a chronic inflammatory condition that effects oral mucous membranes with a variety of clinical presentations including reticular, atrophic, plaque and ulcerative lesions. Corticosteroid is one of the effective therapy for OLP in reducing the sign and symptoms of this disease, but this therapy have a serious side effect, therefore to administering one must consider the patient?s systemic condition. We reported a case of OLP in 52 years old female patient who has no history of diabetes mellitus and unknown glucose level. Management of this patient included application of corticosteroid swish, topical 0.05% clobetasol propionate and 0,1% triamcinolone acetonide, antimycotics, improvement the oral hygiene status and referral to internal medicine specialist. The next treatments plan challenging because unstable blood glucose level which in turn effects the drug choice and teeth extraction plan. We concluded that the treatment of OLP requires a complete assessment of medical status and lab studies specially on the first visit so the drug selection with corticosteroid therapy and the treatment planning of predisposing factor are effective in reducing the sign and symptoms of OLP with minimum systemic side effect.

Oral lichen planus (OLP) is a chronic inflammatory condition that affects the oral mucous membranes with a variety of clinical presentations, including reticular, atrophic (desquamative gingivitis) and ulcrative lesions. Treatment aims primarily to reduce the length and severity of symptomatic outbreaks. We report a case of OLP in 53 years old female patient with hypertension as underlying disease. The patient had been treated with nifedipine and reserpine for twelve years. Management of the patient included the application of 0.05% clobetasol propionate in a custom tray for erosive gingival lesions, nutritional supplementation, oral hygiene promotion and consultation to internal medicine specialist. The improvement of OLP requires a complete assessment of the medical status and elimination of local exacerbating factors. Systemic drug therapy is needed if OLP is suspected as the cause of oral lichenoid lesion. Changing to other drug regimes may also become necessary for improved immune status.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 353-357 Oral squamous cell carcinoma represents more than 90% of all oral cancers. Ten percent of the cases are found on the buccal mucosa and the gingiva. The World Health Organization defines a premalignant or precancerous lesion as a morphologically altered tissue in which cancer is more likely occur and includes oral leukoplakia, oral erythroplakia, and possibly oral lichen planus (OLP). The purpose of this study was to discuss the possibility of malignant transformation of OLP. The potency of OLP as a premalignant lesion is still an ongoing controversial discussion in the literature. The report a case of oral squamous cell carcinoma located on the left buccal mucosa accompanied by oral lichenoid lesions on the right buccal mucosa, lower labial mucosa, and left buccal mucosa. These findings led to a possibility of malignant transformation of the oral lichenoid lesions. Unfortunately, biopsy on the lichenoid lesions was not performed. Therefore, a definitive diagnosis of OLP could be established and the possibility of the lesions being dysplastic remained unclear. This study concluded that biopsy is mandatory to establish a definitive diagnosis of OLP and to investigate the possibility of dysplasia. It is necessary to perform examination of genetic alterations in dysplastic OLP in order to assess loss of heterozygosity (LOH), which may help to consider the risk of malignant transformation.
