A Deceiver Feature of SCC: A Rare Case of Oral Lichen Planus Malignant Transformation

Oral Lichen Planus (OLP) is a chronic inflammatory disease of the oral mucosa. Patients with OLP have an increased risk of developing Oral Squamous Cell Carcinomas (OSCCS), with a reported malignant transformation rate between 0% and 5.3%. Current case report is a patient with a primary feature of erythematouse lichen planus but the last feature of OSCC. The nature of OLP favors an active-quiescent-active course. The active course may happen after direct irritation, pchycological stress, medication use, and systemic disease. In our case, presumably, emotional stress was a trigger for exacerbating the disease. Worsening ulceration and induration are clues of malignant transformation and carefull follow up sessions are mandatory for these patients.
