Ulcers and vesicles

Minor aphthous ulcers are under 1 cm, form on movable nonkeratinized mucosa and heal in 7-14 days without scarring; major aphthae are larger, last weeks and scar. Recurrent herpes favors keratinized tissue such as the palate, attached gingiva and lip. Primary herpetic gingivostomatitis brings fever and painful gingivitis with vesicles, and erythema multiforme causes target skin lesions and crusted lips.
