Cutaneous<unk>  lesions typically resolve within six months to a year. However, some variant such as the hypertrophic variant might persist for years if left untreated or unmonitored. It is found that cutaneous<unk>  does not carry a risk of skin cancer. In contrast to cutaneous<unk> , which is self limited,<unk>  lesions in the mouth may persist for many years, and tend to be difficult to treat, with relapses being common. Although this condition was first described almost a century ago, it has been reported that its associated oral cancer risk has been exaggerated. Overall, it is found that patients with erythematous or erosive oral<unk>  have a higher risk of oral squamous cell carcinoma compared to patients diagnosed with other variants. Due to the possibility that oral<unk>  may increase risk for oral cancer, patients with oral<unk>  are encouraged to avoid activities known to increase the risk for oral cancer, such as smoking and alcohol use. Patients with oral<unk>  should be followed-up at least every 6 to 12 months, to assess the disease activity, changes in symptoms or even detect early signs of malignancy.
