Oral lichen planus versus epithelial dysplasia: difficulties in diagnosis
Oral lichen planus and oral lichenoid lesions; A critical appraisal with emphasis on the diagnostic aspects. Lichenoid lesions of oral mucosa. Proliferative verrucous leukoplakia and precancerous conditions In: Lichenoid reaction associated with amalgam or other dental restorations can be differentiated clinically on the basis of its unilateral presentation and its topographical relation with the amalgam restoration.
A comparison with lichen planus. Segregation of these lichenoid lesions is mandatory as each may embody a distinct disease entity in terms of cause, diagnosis and prognosis. Any histological findings showing dysplastic changes will make diagnosis as lichenoid dysplasia than oral lichen planus.
Morphometric analysis of suprabasal cells in OLP showed increase in cell size when compared to other white lesions. After 63, 32, and 56 mean 50 months, carcinoma developed in all three. It does not imply dysplastic changes in lichen planus.
J Oral Pathol Med In retrospect, the initial biopsy specimens of two patients exhibited lichenoid dysplasia, whereas that of the third showed only lichenoid mucositis. Articles from Journal of Clinical and Dysplaisa Research: Lesions in erythema multiforme are more common in anterior part of the oral cavity; blood crusted ulceration on lips are almost exclusively seen in erythema multiforme.
However, in view of both the common occurrences of OLP and unresolved issues regarding its premalignant potential, the need for close follow-up of lesions with clinical lichenoid features clearly is illustrated 2.
Scully C, el-Kom M. Dysplasiaa a dyspalsia of patients justified? J Can Dent Assoc. This condition manifests characteristics that are similar to the ones encountered in oral lichen planus, but it also presents altered epithelial cell maturation patterns, thus excluding lichen planus from the diagnostic possibilities.

All the values were noted and statistically analyzed. Lichen planus, Lichenoid reaction, Squamous cell carcinoma. Systemic lupus erythematosus presenting with oral mucosal lesions: The concern around the malignant potential of oral lichen planus is much more related to diagnostic difficulties than to the nature of the condition itself.
The pathogenesis of these two lesions is entirely different – in lichen planus the lichenoid infiltrate represents cell mediated immune response incited by different antigens whereas in LD, it represents immune surveillance mechanism against atypical epithelial cells [ 2 ]. Considerable controversy exists in the literature as to whether oral lichen planus has an inherent predilection to become malignant.
Need of the study OLP has been considered a premalignant condition requiring a recall program and proper follow up, which require substantial economic resources and is a potential problem in developing nations like ours.

J Clin Pathol ; J Dermatol Surg Oncol ; J Am Dent Assoc ; In view of malignant transformation, biopsy is mandatory for LD and erosive and atrophic forms of lichen planus.
Clinical management and malignant transformation. The oral lesions of Lichen planus. Abstract Lichenoid Dysplasia LD is often regarded as lichen planus with dysplastic features, as it mimics lichen planus clinically and histologically. It has also been suggested epithelial dysplasia with lichenoid features is a distinct histopathologic entity with a true malignant predisposition 2.
