Treating erosive lichen planus with griseofulvin: a report of four cases

Lichen planus is one of the most common dermatologic diseases involving the skin and oral mucous membranes. It may occur anywhere in the oral cavity. Erosive lichen planus has been reported to undergo malignant transformation, making definitive diagnosis, treatment, and followup essential. The purpose of this study was to establish the effectiveness of griseofulvin therapy on erosive lichen planus and to provide an alternative to steroid therapy. The results of this study revealed that griseofulvin had little or no effect on pain, pigmentation, or disappearance of erosive lichen planus and did not protect the patient from further recurrences.     

A multicenter study of oral lichen planus in Thai patients

Abstract Aim: Oral lichen planus is an oral mucosal disease that affects middle‐aged patients. The characteristics of oral lichen planus in Thai patients from a multicenter were studied. Methods: Data of 533 patients from the oral medicine clinics at Chulalongkorn and Mahidol (central Thailand), Chiang Mai (northern Thailand), and Khon Kaen (northeastern Thailand) universities during 2002–2007 were analyzed. The diagnosis of patients with oral lichen planus was clinically and/or histopathologically confirmed. Results: There was a greater number of female patients than males (4:1). There were significant differences in age, sex, and some systemic diseases among the oral lichen planus patients from the three centers. Burning sensation was the most common symptom (72.9%), followed by pain (26.5%), roughness (6.4%), and then no other symptoms (7.9%). The most common site of lesions was found at the buccal mucosa (87.1%). Atrophic oral lichen planus was common in Thai patients. There were significant differences in the types of oral lichen planus, including reticular, atrophic, and ulcerative oral lichen planus among these patients from the three centers (P = 0.000). Nine cases (1.7%) showed dysplasia, but one case (0.2%) developed squamous cell carcinoma. Conclusion: Patients with oral lichen planus from the central, northern, and northeastern parts of Thailand presented with distinct characteristics. The malignant transformation of oral lichen planus was low in Thai patients.     

Oral lichen planus: a condition with more persistence and extra‐oral involvement than suspected?

Background: Lichen planus is a relatively common and often studied chronic mucocutaneous condition. Reports detailing certain aspects relevant to patients affected have been lacking or inconsistent. Methods: A questionnaire‐based survey was employed to assess the duration of oral lesions and the prevalence of self‐reported potential extra‐oral manifestations associated with oral lichen planus in 87 patients. All patients had recognized clinical features of oral lichen planus, and most had had histopathological confirmation following oral biopsy. Results: We report the findings of a preliminary survey which assessed the duration of oral lesions and the prevalence of extra‐oral lesions consistent with lichen planus in patients presenting with oral lesions. The study confirmed the chronic nature of oral lichen planus and the rarity of spontaneous resolution. Most subjects had experienced symptoms for one to ten years (66 patients; 75.8%). Approximately 40% (36 patients) of the sample reported clinical features suggestive of extra‐oral manifestations of lichen planus by the time that their oral lesions were apparent. The most commonly reported extra‐oral manifestations involved the nails (27.6%, 24 patients). 25.3% (22 patients) reported a persistently sore throat suggestive of oesophageal or pharyngeal involvement. Skin (17.2%, 11 patients), and genital (10.3%, 9 patients) involvement was relatively infrequently reported. Most patients reported extra‐oral lesions at only one site. Conclusions: The survey results suggest that in patients with oral lichen planus oral lesions persist for a prolonged period, and that extra‐oral lesions may be more common than suspected. However, further studies involving specialists to examine extra‐oral sites are required.     

口腔扁平苔藓与牙周炎关系的研究进展

牙周炎为发生在牙周组织的慢性感染性疾病,同时口腔扁平苔藓也是口腔粘膜的常见疾病。临床上大多数口腔扁平苔藓患者牙周状态差,并且牙周基础治疗对其有一定疗效;在发病机制上二者都与免疫、遗传及心理精神因素等有关。牙周炎与口腔扁平苔藓这两种慢性炎症疾病可同时存在或伴随患者终身,维护好牙周健康已成为口腔医学必须面对的现实。本文对近年来牙周炎与口腔扁平苔藓的关系进行回顾总结,为牙周病和口腔扁平苔藓的进一步研究奠定基础。     

Effect of dental plaque control on gingival lichen planus

Eleven patients, all women, aged 43 to 76 years, with atrophic or ulcerative lichen planus lesions of gingiva were included in this preliminary study. After initial examination, the patients received an intensive individual hygiene treatment. The patients continued using the most appropriate, atraumatic method resulting in the best possible oral hygiene over a 1 year period during which they were seen for follow-up examinations at 3-month intervals. The mean plaque scores decreased after the initial treatment followed by an increase. The mean scores for severity of subjective symptoms and for type and extension of lesions initially decreased with the plaque scores and remained lower throughout the study. It is concluded that in some cases both subjective and objective improvement of atrophic and ulcerative gingival lichen planus may be obtained by means of intensive oral hygiene procedures although such procedures do not remove the basic cause of lichen planus. However, further studies are needed to examine the role of dental plaque control in patients with oral lichen planus.
