Oral Lesions and Prognosis Quiz

Poor prognosis leukoplakia often presents with a speckled appearance (combining erythroplakia and leukoplakia), a nodular surface, exophytic growth, increased firmness or induration, and unexplained hemorrhage. Common sites include the lateral border of the tongue, ventral surface of the tongue, floor of the mouth, and retromolar areas.

Leukoplakia can be managed with conservative measures including smoking cessation and balanced diet, with a 70% chance of regression. In contrast, proliferative verrucous leukoplakia has a high malignant transformation rate (50-70%) and a strong tendency to recur after treatment.

Management for mild dysplasia includes smoking cessation, alcohol reduction, a balanced diet rich in fruits and vegetables, and treatment of any candidal infections. Regular monitoring every 6 months is also crucial.

<p>Moderate and severe dysplasia necessitates surgical excision or laser removal to eliminate the dysplastic tissue and minimize the risk of progression.</p> Signup and view all the answers

<p>Proliferative verrucous leukoplakia typically begins as a white patch that gradually develops into multiple exophytic, wart-like lesions. It is primarily observed in the buccal mucosa, gingiva, and tongue.</p> Signup and view all the answers

<p>Submucous fibrosis is characterized by progressive fibrosis affecting the hard and soft palate, fauces, and cheeks, leading to restricted mobility. This differs from leukoplakia, which primarily affects the mucosal surface. Betel nut chewing (areca nut) is the primary etiological factor associated with submucous fibrosis.</p> Signup and view all the answers

<p>The high recurrence rates associated with proliferative verrucous leukoplakia and submucous fibrosis necessitate long-term follow-up and multiple surgical interventions to control the lesions and minimize the risk of malignancy.</p> Signup and view all the answers

<p>Proliferative verrucous leukoplakia is typically treated through surgical resection, although there's a high rate of recurrence, often necessitating multiple interventions. Submucous fibrosis treatment primarily focuses on preventing further progression through cessation of betel nut chewing and supportive measures like corticosteroid therapy. The challenge in both conditions is maintaining long-term control and managing persistent lesions.</p> Signup and view all the answers
