Minor aphthous ulcers are recurrent and appear on movable mucosa. They are 3 to 5 mm in diameter and have a yellowish-white fibrin center surrounded by an erythematous halo. Major aphthous ulcers are deeper in the tissue, are larger (5 to 10 mm), take much longer to heal, and often heal with scarring. Sutton disease is the same as major aphthous ulcers. Herpetiform aphthous ulcers are very tiny (1 to 2 mm). The size of this type of aphthous ulcer is similar to the size of ulcers caused by the herpes simplex virus.
