These areas thicken with progression of the condition and may resemble leukoplakia lesions, especially when they extend to the transition zone of the lip. In addition, there may be loss of sharpness between the vermilion border of the lip and skin where chronic ulcers can progress to squamous cell carcinoma (Sarmento et al., 2014;Zanetti et al., 2007).
