REPORT OF A CASE
A 43-year-old man was well until March 1989, when he developed 2 painful "sores," one on his lower lip and the other on his tongue. They were followed by large ulcers, which in a few weeks healed with scarring (Figure 1). Since the first episode, he has had recurrent episodes of similar lesions, involving not only the lip and tongue but also the buccal mucosa, soft palate, and uvula. He had no eye or joint complaints, and he had no gastrointestinal complaints, except for occasional loose stools. When the patient came to the dermatology clinic in August 1991, he had scarring and distortion of the lower lip, tongue, buccal mucosae, and uvula. He was unable to fully open his mouth because of the scarring (Figure 2). Biopsy specimens were obtained from the lip (Figure 3) and salivary gland (Figure 4).What is your diagnosis?
