There is a male predilection, presumably due to the commonly implicated risk factors, smoking and alcohol. It presents as a white plaque with generally well-demarcated borders. Early lesions present as homogenously smooth and thin, and more advanced lesions may present with nodular, verrucous, or even partially erythematous components erythroplakia.
The area of hyperpigmentation located posteriorly may represent a coexisting melanotic macule or an unusual example of post-inflammatory hyperpigmentation PIH , which is most characteristically associated with lichen planus. Lichen Planus.
Lichen planus is an immunologically mediated mucocutaneous disorder. It tends to occur in middle-aged patients with female predominance.

Skin lesions appear as purple, pruritic, polygonal papules. Oral lesions may be white, red, or ulcerative. The reticular type presents with classic Wickham striae, typically on the posterior buccal mucosa bilaterally, and is frequently asymptomatic. Other common surfaces involved are the ventrolateral tongue and the gingiva. Erythematous and ulcerative presentations may be symptomatic. For asymptomatic cases, no treatment is required.
Topical or systemic corticosteroids are recommended for symptomatic patients. Disease course is variable but my be waxing or waning. Oral and maxillofacial pathology. Elsevier Health Sciences; Greenberg MS, Glick M Hamilton, Ont.

Identify the abnormality and provide your diagnosis. Subpontic Hyperostosis. There is a well-defined radiopaque entity noted at the crest of the edentulous alveolar ridge. Occasionally, irritation from the pontic could produce excessive bone formation, which would appear as a radiopaque entity under the pontic.
Hence the entity noted in the bitewing is termed a subpontic hyperostosis. Mandibular Tori. Mandibular tori are located on the lingual aspect; on radiographs they appear to superimpose over the roots of the premolar and molar teeth. However, in the bitewing radiographs shown, the radiopaque entity noted is below the pontic. The lesion is well corticated, round to ovoid in shape. No evidence of root resorption or expansion is noted.
Clinical examination proved that teeth are vital. Lateral Radicular Cyst.

Radiographically there is no evidence of loss of lamina dura and PDL space. Coronally, no evidence of pulpal involvement is observed on the radiographs. Clinical examination should reveal teeth to be nonvital. Lateral Periodontal Cyst.
Based on the location and radiographic presentation, this fits the description of lateral periodontal cyst. The clinical exam should reveal vital teeth.

Lateral periodontal cysts typically are noted in mandible, canine- premolar region. Lateral periodontal cyst if they are multiple they are termed as botryoid type.
