<p>The Dynamics of Oral Lichen Planus and Lichenoid Mucositis<br>Lieutenant Rachel L. Werner DC USN, Commander S. Marc Stokes DC USN, Colonel Christopher Fielding DC USA<br><br>Introduction<br>Lichenoid mucositis is a noncommittal term referring to a wide range of mucosal lesions which closely mimic oral lichen planus both clinically and histologically, yet may represent a different pathoetiology altogether. In general, most oral lichenoid reactions represent a common end point in response to a myriad of extrinsic agents (drugs, allergens) or altered immunologically-mediated mucocutaneous processes.<br><br>The clinical appearance of lichenoid mucositis is often described as having a gray to white interlacing reticular pattern set within an erythematous background. Focal atrophic erythema-tous areas exhibiting central ulceration with a peripheral radiating pattern of hyperkeratotic striae may be observed. In addition, keratotic plaques can be present which may create a diagnostic dilemma in clinically differentiating from a bona-fide leukoplakia. Clinically, it is not unusual for a patient to present with multiple patterns.<br><br>Oral lichen planus, a relatively common and perhaps underrecognized mucocutaneous disorder, shares many clinical and histologic features within the spectrum of the “lichenoid mucositis” diagnostic umbrella. Due to the variable morphologies of oral lichen planus, one must consider a broad differential diagnosis and have a thorough understanding of the multifaceted clinical presentations. Definitive diagnosis often requires a strong clinical correlation, thorough medical history review and supportive histopathology.
