Lichenoid dysplasia is a lichenoid features with epithelial dysplasia clinically and histopathologically similar to oral lichen planus. It can be clinically mistaken for oral lichen planus, but has histopathologic features of dysplasia and a true malignant predisposition. The clinician should be able to differentiate between oral lichen planus and lichenoid dysplasia for the proper management. We experienced a 75-year-old man with erosive, erythematous lesion on the left buccal mucosa previously diagnosed as oral lichen planus. He underwent surgical excision and the final histopathological result confirmed it to be lichenoid dysplasia with massive candidal infection. We report this case with a review of the related literature.

Lichen planus is a unique inflammatory cutaneous and mucous membrane reaction pattern of unknown etiology. Lichen planus of the soles generally occurs as an isolated phenomenon. The lesions differ from classic lesions of lichen planus in that the papules are larger and aggregate into semitransluecent plaques with a globular waxy surface. We report a 38-year-old female patient with lichen planus of right sole. The lesion shows erythematous eroded patch, swelling and severe pain. We thought that she might have envolved erysipelas. So, we gave her oriental medicine and antibiotics, so she was improved. But after long walking, lesion began to getting worse. There appeared oozing, ulcer, pus, pain and swelling in her lesion. We gave her oriental medicine and wet dressinf. But it didn't work.

Lichenoid dysplasia is a lesion similar to oral lichen planus with epithelial dysplasia. It can be clinically mistaken for oral lichen planus, but has histologic features of dysplasia and a true malignant predisposition. It is not a variant or transitional form of lichen planus but, instead, represents a distinct entity that has a true potential for malignant transformation. In addition to abnormal epithelial maturation and cytology, lichenoid dysplasia exhibits other histologic features that separate it from oral lichen planus. Lichenoid dysplasia and lichen planus share many clinical and microscopic features, leading to the frequent misdiagnosis of unrecognized lichenoid dysplasia as lichen planus. We experienced a case of lichenoid dysplasia in the oral mucosa. We treated this patient with surgical excision. The patient has now been followed for two months. It is important to recognize this precancerous condition and inspect the excision site and remaining oral mucosa during long-term follow-up.

편평태선은 작고 편평한 다각형의 구진을 피부나 점막에 보이는 만성 염증성 질환으로 편평태선을 유발하는 원인은 명확하지는 않으나, 피부나 점막에서의 항원변화가 세포매개성 면역반응을 유도하여 발생하는 것으로 생각되어진다. 구강편평태선은 초기에는 양성 병소로 생각되었으나 세계보건기구에 의해 전암 병소로 분류되었다. 구강편평태선이 악성화되는 단계는 명확하게 밝혀지지 않았으며, 편평태선등의 만성 염증성 질환은 구강암 발생에 있어 일반적인 위험 요인(예: 흡연, 음주)과 관계없이 악성 발현을 보인다. 구강편평태선의 악성전이는 여러 문헌에서 논란을 보이나, 0.5%에서 5%까지 보고되었다. 구강편평태선의 악성 전이는 특정 임상적 양상, 과각화나 미란성에서 더 높은 비율로 발생한다. 구강편평태선의 악성 전이는 예후가 불량하므로 예후의 개선과 조기 진단을 위하여 임상가는 일년에 최소 일회에서 2회까지 추적 조사를 해야 한다. 본 증례 보고에서는 중년의 여성에게서 십수년간 지속된 구강편평태선에서 발생한 편평상피암종을 살펴봄으로써, 임상가가 유념해야 할 구강편평태선의 악성 변이에 대한 고찰 및 진단시와 추적 조사시에 고려사항을 고찰하자고 한다.

Oral lichen planus is a chronic inflammatory disease of adult onset. Current therapeutic modalities for severs oral erosive lichen planus are still generally unsatisfactory. A case of 53 year-old female patient with severe oral erosive lichen planus is reported in which the lesion showed the dramatic improvement without serious adverse effects upon using griseofulvin.

Oral lichen planus is a premalignant chronic inflammatory mucosal disorder with unknown etiology. It is a multifactorial disease and in addition to genetic background, infections, stress, drug reactions are suggested as risk factors. Helicobacter pylori which is involved in development of many gastrointestinal lesions may also be implicated in oral lichen planus induction. This is of clear importance for cancer prevention and the present study was performed to determine any association between H. pylori infection and oral lichen planus in southwestern Iran. Anti H. pylori IgG levels were determined in 41 patients and 82 sex-age matched controls. The results showed no association between H. pylori infection and oral lichen planus (51% in patients vs. 66% in control). or any of its clinical presentations.

Lichen planus is a chronic disease characterized by bilateral and multiple lesions on the skin or oral mucosa. Lichen planus is caused by immune mediated degeneration along the border between epithelium and connective tissue. The incidence of oral squamous cell carcinoma in patients diagnosed with oral lichen planus (OLP) is reported to be between 0.4%-5.6% in different studies and the World Health Organization has categorized lichen planus as "a potentially malignant disorder". However, the correlation between OLP and oral cancer still remains controversial as some reported that the reason for increased incidence of squamous cell carcinoma in OLP patient is misdiagnosis of dysplastic lesion as OLP. This report aims to discuss the correlation between OLP and oral cancer through a case of middle aged woman diagnosed with OLP who was successfully treated but developed squamous cell carcinoma 8 years later.

Objectives: The objective of this study was to identify salivary and serum concentrations of interleukin (IL)-8, IL-6, and tumor necrosis factor alpha ($TNF-{\alpha}$) in patients with oral lichen planus, oral leukoplakia, oral submucous fibrosis, and healthy controls. Materials and Methods: Patients selected included 54 oral lichen planus (41 to 65 years), 50 oral leukoplakia (42 to 65 years), 51 oral submucous fibrosis (41 to 65 years), and 50 healthy controls (42 to 65 years). Oral lichen planus, oral leukoplakia, and oral submucous fibrosis cases were diagnosed using histopathological analysis. Salivary and serum cytokine concentrations were measured using enzyme-linked immunoassay kits in all subjects. Results: The levels of serum and salivary $TNF-{\alpha}$, IL-6, and IL-8 were statistically significantly increased in oral leukoplakia, submucous fibrosis, and lichen planus in contrast to normal healthy subjects (P<0.05). Serum and salivary correlation analysis revealed strong and highly significant correlations for $TNF-{\alpha}$, IL-6, and IL-8 in all groups (r=0.72-0.82, P<0.05). Conclusion: Salivary and serum cytokines were also elevated when analyzed in oral precancerous lesions. Thus, salivary and serum IL-8, IL-6, and TNF-${\alpha}$ levels might act as diagnostic markers for detection of oral precancer.

Current therapeutic modalities for severe oral lichen planus are generally unsatisfactory. Steroid treatment of lichem planus has been reported in the dermatology literature and dental literature, but few reports mention its efficacy for oral lesions. Some cases of severe erosive oral lichen planus revealed good response to this agent. So the author report two cases of erosive oral lichen planus treated with 0.05%. Dexamethasone methyl cellulose mouth wash and two intralesional injections of Triamcinolone acetonide suspension 0.2 mls, one week apart. 1. Subjective improvement was noticed in 4-5 days by two patients. 2. Objective improvement, however, was delayed and became apparent at several weeks 3. Continued improvement was noted in all patients.

편평태선은 면역 매개 점막피부 질환으로 병인은 여전히 알려져 있지 않고, 중년의 백인 여성에서 흔히 발생하고 구강점막에서 증상이나 징후가 생기기도 한다. 편평태선의 피부 병소는 가려움을 유발하나 자기 제한적이고, 구강편평태선의 구강 병소는 만성적이고 좀처럼 스스로 치유되지 못하고, 드물긴 하나 잠재적으로 전암 병소로 발전할 수 있다. 구강편평태선은 비록 비치태 연관 질환이나 통증, 출혈로 인해 적절한 치태 조절이 어렵게 되어 치태 연관 질환을 야기할 수 있고, 작열감, 자발적인 출혈 등 구강편평태선과 관련된 점막 증상이 축적된 치태에 의해 더욱 악화될 수 있다. 따라서 구강편평태선 환자에서 구강편평태선 자체의 약물적 치료뿐만 아니라 적절한 구강 위생 관리, 치석 제거 등의 치주 치료가 동반되어야 한다. 본 증례에서는 구강편평태선 환자에서 국소적인 코르티코스테로이드 치료뿐만 아니라 구강 위생 교육을 포함한 치주 치료를 통해 증상 및 징후를 개선시키고 재발 방지를 도울 수 있었다.
