Clinical Findings

The left lateral border of tongue showed evidence of an ulcer surrounded by a rim of white plaque (Figure 1). The dorsal and right lateral border of tongue showed no evidence of similar lesions. The central part of right buccal mucosa was white and rough (Figure 2). It had white striae interlacing to produce a reticular pattern. There was no evidence of ulceration. The left buccal mucosa appeared relatively normal with a hint of white striae.
